A CME PASSED BY EARTH YESTERDAY: During the late hours of March 10th, a CME passed by Earth. The near miss sparked auroras in northern Europe bright enough to see through city lights. Another CME is coming, but it won't miss. Details below.

THE NEXT CME WON'T MISS: A full-halo CME is heading directly for Earth. ETA: March 13th. Coronagraphs onboard the Solar and Heliospheric Observatory recorded the storm cloud leaving the sun just hours ago:

SpaceWeather updates - Page 4 Fullhalo_opt

https://spaceweather.com/images2022/11mar22/fullhalo_opt.gif

Note: The bright "star" at the lower right of the sun is Jupiter.

This CME is the result of a long duration C2-class solar flare near sunspot AR2962. Normally, C-class flares are not considered to be strong. However, this one lasted nearly 12 hours, allowing it to pump plenty of energy into the CME.

Moderately-strong G2-class geomagnetic storms are possible when the CME arrives. NOAA analysts are modeling this CME now, and improved predictions may be available soon.

SOLAR FLARE AND RADIO BLACKOUT: Departing sunspot AR2964 just produced an M2-class solar flare: movie. The explosion on March 11th at 2232 UT caused a brief shortwave radio blackout over the Pacific Ocean. Mariners and ham radio operators may have noticed unusual propagation effects at frequencies below ~20 MHz. Solar flare alerts: SMS Text.

GEOMAGNETIC STORM WATCH (CATEGORY G2): A full-halo CME is heading directly for Earth. ETA: late on March 13th. Coronagraphs onboard the Solar and Heliospheric Observatory (SOHO) recorded the storm cloud leaving the sun earlier today:

This CME is the result of a long duration C2-class solar flare near sunspot AR2962. Normally, C-class flares are not considered to be strong. However, this one lasted nearly 12 hours, allowing it to pump plenty of energy into the CME.

Moderately-strong G2-class geomagnetic storms are possible after the CME arrives. During such storms, naked-eye auroras may appear in northern-tier US states from Maine to Washington. Power grids and satellites will experience little to no effect, however.

A new model of the CME from NASA pinpoints the arrival time around 1800 UT on March 13th. In this animation, the yellow dot is Earth:

SpaceWeather updates - Page 4 Nasamodel_crop_strip_opt

https://spaceweather.com/images2022/11mar22/nasamodel_crop_strip_opt.gif

Geomagnetic storms, if they materialize, could spill into March 14th, making this a Pi Day geomagnetic storm. That's appropriate. After all, auroras form a circle around Earth's magnetic poles.

Take another look at the NASA model. The CME hits Venus less than a day before it reaches Earth. The CME won't spark a geomagnetic storm on Venus. It can't; the planet has no internally-generated global magnetic field. Instead, the impact will erode a small amount of atmosphere from Venus' unprotected cloudtops.

Geomagnetic storms: One of the perks of living on Earth. High latitude sky watchers should be alert for auroras on March 13-14.

CME IMPACT SPARKS GEOMAGNETIC STORM: As predicted, a CME hit Earth's magnetic field today, March 13th. The impact has sparked a moderately strong G2-class geomagnetic storm. When the CME arrived, "the sky exploded," reports John Dean, who sends this picture from Nome, Alaska

AN ASTEROID JUST HIT EARTH: Discovered-Photographed-Destroyed. All three things happened to asteroid 2022 EB5 in quick succession on March 11th. Hungarian astronomer Krisztián Sárneczky discovered the asteroid at 19:24 UT. Italian astronomer Enrico Pettarin photographed the asteroid at 20:28 UT:

SpaceWeather updates - Page 4 2022eb5_strip_opt

The asteroid destroyed itself at ~21:22 UT when it hit Earth's atmosphere off the coast of Iceland, disintegrating harmlessly as a bright fireball. The entire sequence of events took less than 2 hours.

The explosion was detected by Comprehensive Nuclear Test Ban Treaty Organization infrasound stations in Greenland and Norway. Combining data from the two locations, University of Western Ontario astronomer Peter Brown estimates that "the asteroid exploded with an energy close to 2 kilotons of TNT. Assuming a speed of 15 km/s, it must have been about 3 m in diameter," he says.

ANOTHER CME IS COMING: On March 13th, an unstable filament of magnetism in the sun's far-southern hemisphere exploded. The resulting CME could deliver a glancing blow to Earth's magnetic field on March 17th. Minor G1-class geomagnetic storms are possible when the CME arrives. Aurora alerts: SMS Text.

CME IMPACT SPARKS BRIGHT AURORAS: As predicted, a CME hit Earth's magnetic field on March 13th. The impact sparked a moderately strong G2-class geomagnetic storm, which lasted more than 12 hours. "It was the best Northern Lights show for years," reports Jónína Óskarsdóttir, who sends this picture from Fáskrúðsfjörður, Iceland:

MAGNETIC FILAMENT ERUPTION: A filament of magnetism in the sun's northern hemisphere (N16E10) erupted this morning, March 20th at 0745 UT: movie. The explosion produced a C4-class solar flare, caused a Type II solar radio burst, and sent a shock wave racing through the sun's corona. Explosions with these characteristics usually produce a CME as well. Confirmation awaits fresh data from SOHO coronagraphs. Aurora alerts: SMS Text.

THE FIRST AURORAS OF SPRING: Today is the first day of spring in the northern hemisphere. In Alaska, the season began with an outburst of green. "Happy Equinox, everyone!" says Todd Salat who sends this picture from Broad Pass in the Alaska Range:

SpaceWeather updates - Page 4 Springgreen_strip

https://spaceweather.com/images2022/20mar22/springgreen_strip.jpg

"Auroras kicked in just after local midnight (08:00 UTC) at the very beginning of the Spring Equinox," says Salat. "A lunar halo rising over the mountains added spice and balance."

The display was caused by a passing CME. The storm cloud did not actually hit Earth. However, NOAA's DSCOVR spacecraft detected ripples of magnetism from the near miss. Those ripples touched Earth's magnetosphere and sparked the display.

YET ANOTHER GLANCING-BLOW CME: Another CME is heading for Earth, and it's a little off target. A glancing blow (or near miss) is possible during the late hours of March 23rd, according to NOAA forecasters. This will be the 3rd time in the past week that a CME has almost landed a direct hit. Even a near miss can produce bright Arctic auroras. Best case scenario for auroraphiles: A minor G1-class geomagnetic storm. Aurora alerts: SMS Text.

AURORAS LOVE EQUINOXES: A CME passed near Earth yesterday, March 20th. It didn't hit. But at this time of year a near miss is enough, because auroras love equinoxes. Christopher Mathews witnessed a beautiful display from his backyard in Hraunborg, Iceland:

SpaceWeather updates - Page 4 Iceland_strip

https://spaceweather.com/images2022/21mar22/iceland_strip.jpg

"My expectations last night were pretty minimal," says Mathews. "The hoped-for CME impact was mostly a clean miss. But because it was the equinox (when Northern Lights seem to come out more often), I decided to watch the skies anyway, and I'm glad I did!"

It's true. Auroras really do love spring. Researchers call it the "Russell-McPherron effect." During the weeks around equinoxes, cracks form in Earth's magnetic field, allowing solar wind to enter. Even a weak stream of solar wind or an off-target CME can spark a good display at high latitudes.

Another off-target CME is on the way. ETA: March 23th. Thanks to Russell and McPherron, it doesn't need to land a solid blow for skies to turn spring green.

NEW SUNSPOT PRODUCES SOLAR FLARE: A new sunspot emerging over the sun's northeastern limb exploded today, March 22d @ 1242 UT, producing a C7-class solar flare: movie. X-rays ionized the top of Earth's atmosphere which, in turn, caused a brief shortwave radio blackout over the Atlantic Ocean. Frequencies affected were mostly below 15 MHz. Solar flare alerts: SMS Text.

FARSIDE SOLAR ACTIVITY: Yesterday something exploded on the far side of the sun. Coronagraphs onboard the Solar and Heliospheric Observatory (SOHO) recorded a massive CME emerging from behind the sun's southeastern limb:

SpaceWeather updates - Page 4 Farside_cme_opt

SpaceWeather updates - Page 4 Farside_cme_opt

https://spaceweather.com/images2022/21mar22/farside_cme_opt.gif

A few hours later, it happened again. If Earth had been in the line of fire, we would now be anticipating a strong geomagnetic storm.

Although these explosions were not Earth directed, they nevertheless managed to touch our planet. Shortly after the first CME emerged, NOAA's GOES-17 satellite detected a surge of energetic protons

SOLAR TSUNAMI AND CME (UPDATED): Sunspot AR2974 exploded yesterday (March 25th @ 0526 UT), producing an M1-class solar flare. The explosion also sent a shadowy shock wave rippling through the sun's atmosphere--i.e., a "solar tsunami." Watch the movie. Newly arriving data from SOHO confirm that the explosion did hurl a full-halo CME toward Earth. NOAA forecasters anticipate G1-class geomagnetic storms when it arrives on March 27th. Stay tuned for updates.Solar flare alerts: SMS Text.

THE THERMOSPHERE IS HEATING UP: Solar Cycle 25 is intensifying--and Earth's upper atmosphere is responding.

"The Thermosphere Climate Index (TCI) is going up rapidly right now," reports Linda Hunt of Science Systems and Applications, Inc. "It has nearly tripled in the past year."

TCI is a number published daily by NASA, which tells us how hot Earth's upper atmosphere is. The thermosphere, our atmosphere's highest layer, literally touches space and is a sort of "first responder" to solar activity. Hunt created this plot showing how TCI has unfolded during the last 7 solar cycles. Solar Cycle 25 (shown in blue) is just getting started:

SpaceWeather updates - Page 4 Solarcycle_tci_strip

https://spaceweather.com/images2022/24mar22/solarcycle_tci_strip.jpg

"So far Solar Cycle 25 is well ahead of the pace of Solar Cycle 24," notes Hunt. If this trend continues, the thermosphere could soon hit a 20-year high in temperature.

Before we go any farther, a word of caution: This does not mean Earth is about to heat up. The thermosphere is hundreds of kilometers above our heads. Here on the planet's surface we do not feel its heat; summer days are no warmer when TCI is "hot." As Dr. Marty Mlynczak of NASA notes, "energy driving the climate system near Earth's surface is hundreds of thousands of times greater than in the thermosphere." As far as we know, cyclical warming and cooling of the thermosphere by the solar cycle does not affect climate.

Nevertheless, the thermosphere is important. When it heats up, as it is doing now, it also puffs up. Think of a marshmallow held over a campfire. The thermosphere can expand upward so much it actually touches Earth-orbiting satellites. Almost 40 Starlink satellites fell out of the sky earlier this year as a result of aerodynamic drag up there.

GEOMAGNETIC STORM WATCH (G1-CLASS): A[ CME is expected to hit Earth's magnetic field on March 28th. The impact could spark minor G1-class storms with high-latitude auroras boosted by the Russell-McPherron effect. Solar flare alerts: SMS Text.

SUNSPOT GENESIS IN ACTION: Sunspot complex AR2975-AR2976 is turning toward Earth and growing rapidly. This movie from NASA's Solar Dynamics Observatory shows 12 hours of development on March 27th:

In only half a day, the sunspot group added more than a dozen dark cores scattered across 30,000 km of the sun's surface. Newly-created regions of magnetism are now bumping together, + vs. -, setting the stage for explosive magnetic reconnection. If a solar flare occurs, it will be Earth-directed.

Some of the spots in this group are huge, many times wider than Earth. This makes them easy targets for solar telescopes. Michael Teoh of Penang, Malaysia, took this picture using a 9-inch refractor on March 27th:

SpaceWeather updates - Page 4 Spot_strip

The sunspot's dark core is surrounded by a sea of granules--Texas-sized bubbles of plasma that rise and fall on the sun's boiling surface. "I was able to see this level of detail using a Lunt White Light Solar Wedge," says Teoh.

Amateur astronomers are encouraged to monitor this dynamic sunspot group. Expensive solar filters are not required. The sunspots are so big, you can use simple projection techniques to see them with no danger of eye damage.

GEOMAGNETIC STORM WATCH (G2-CLASS): Moderately strong G2-class geomagnetic storms are possible on March 31st when a CME is expected to hit Earth's magnetic field. During such storms, naked-eye auroras can descend into the USA as far south as, e.g., New York and Idaho (geomagnetic latitude 55^o). In fact, the storm might be stronger than predicted. The source of the CME, active sunspot AR2975, has just sent one or two more CMEs right behind it; details below.

MULTPLE CMEs ARE HEADING FOR EARTH: Sunspot AR2975 has been busy. Since yesterday it has exploded more than 17 times (11 C-class flares + 6 M-class). The eruptions have hurled at least two, possibly three, CMEs toward Earth. Click to watch the storm clouds emerge:

SpaceWeather updates - Page 4 Cme_splash

Above: A SOHO coronagraph movie of multiple CMEs on March 28, 2022.

The first CME (1254 UT) has already been modeled by NASA and NOAA. It is expected to hit Earth's magnetic field on March 31st. The second CME (2130 UT) and the potential third CME (2230 UT) are following close behind. They will likely arrive on April 1st. Their combined impact could spark G2- to G3-class geomagnetic storms.

GEOMAGNETIC STORM WATCH (G3-CLASS): Strong G3-class geomagnetic storms are possible during the early UT hours of March 31st when a Cannibal CME is expected to hit Earth's magnetic field. During such storms, naked-eye auroras can descend into the USA as far south as, e.g., Illinois and Oregon (geomagnetic latitude 50^o). North Americans should be alert for auroras after local nightfall on March 30th. The hours before dawn on March 31st are probably best for Europeans.

X-CLASS SOLAR FLARE: Earth-orbiting satellites have just detected an X1.3-class solar flare (March 30 @ 1737 UT). The source is active sunspot AR2975--the same sunspot that has already hurled at least two CMEs toward Earth this week. NASA's Solar Dynamics Observatory recorded the flare's extreme ultraviolet flash:

SpaceWeather updates - Page 4 Boom_strip2

Radiation from the flare ionized the top of Earth's atmosphere, causing a shortwave radio blackout over the Americas. Here is a blackout map. Aviators, mariners, and ham radio operators may have noticed unusual propagation effects at frequencies below 30 MHz.

SpaceWeather updates - Page 4 Blackoutmap

A CME is almost certainly emerging from the blast site. SOHO coronagraphs have not yet detected the cloud, but there is strong circumstantial evidence. For instance, the US Air Force has detected a Type II solar radio burst, a type of natural radio signal generated by CME shock waves. Also, NASA's Solar Dynamics Observatory has imaged a solar tsunami apparently generated by a CME leaving the sun's atmosphere.

THE CME HAS ARRIVED: As predicted, a Cannibal CME hit Earth's magnetic field on March 31st (0210 UT). First contact sparked a G1-class geomagnetic storm with a chance of stronger storms later today as Earth passes through the CME's magnetized wake. Solar wind speed: 520.1 km/sec

Dakota

X-CLASS SOLAR FLARE: Active sunspot AR2975 erupted again on March 30th, producing its strongest flare yet--an X1.3-class explosion. NASA's Solar Dynamics Observatory recorded the extreme ultraviolet flash:

SpaceWeather updates - Page 4 Xcme_strip

This CME will probably reach Earth during the early hours of April 2nd. (NOAA and NASA modeling, now underway, will soon refine the arrival time.) Its impact could trigger G1-class geomagnetic storms, extending a period of geomagnetic unrest expected that began on March 31st with the arrival of a Cannibal CME launched by the same sunspot a few days ago.

GRAZING CME IMPACT: A coronal mass ejection (CME) hit Earth on April 2nd @ 0100 UT. Weak discontinuities in solar wind data suggest a grazing impact. This appears to be the CME launched by an X1.3-class solar flare on March 30th (sunspot AR2975). Minor G1-class geomagnetic storms are possible as Earth's magnetic field reverberates from the glancing blow.

SOLAR RADIO BURST AND RADIO BLACKOUT: Last Wednesday, March 30th, the sun did two seemingly contradictory things at once. It produced a loud radio burst and, at the same time, caused a deep radio blackout. Both were side-effects of an X1.3-class solar flare. First, let's listen to the radio burst: www.spaceweather.com

Click to listen to the radio burst or view the complete dynamic spectrum. https://spaceweather.com/images2022/01apr22/S_X1.3Mar302022_1739UT_22.21MHzAshcraft_01.mp3

The gentle roar of static you just heard emerged from the loudspeaker of a shortwave radio receiver in New Mexico. Amateur astronomer Thomas Ashcraft recorded it. "The sun was well positioned in my radio antennas for the X1.3 solar flare," says Ashcraft. "The left channel of the audio file is 22.2 MHz, the right channel is 21.1 MHz."

This is a Type II solar radio burst. Shock waves from the flare rippled through the sun's atmosphere, creating plasma oscillations that emit shortwave static. Briefly, the sun turned itself into a natural radio transmitter.

While the sun was busy creating radio waves, it was equally busy wiping them out. Radiation from the flare ionized the top of Earth's atmosphere, preventing terrestrial radio stations from bouncing their signals over the horizon as usual. This map shows where manmade signals suddenly faded:

Ashcraft's observatory in New Mexico is located near the middle of the blackout zone. Take another look at his dynamic spectrum. Horizontal lines are terrestrial radio stations. They vanished for about 10 minutes around the time of the flare. The effect is strongest at frequencies below ~20 MHz.

In Gainesville, Florida, radio astronomer Francisco Reyes recorded the blackout as well. "I used an array of 4 dipoles with an FSX-7 radio spectrograph (Radio JOVE)," he says.

This SOHO coronagraph movie shows an asymmetric full-halo CME emerging from the blast site. The bulk of the CME will miss, but not all. A fraction of the storm cloud is likely to strike Earth's magnetic field on April 5th or 6th. Even a glancing blow could spark a G1-class geomagnetic storm.

See all the snow at the beginning of the coronagraph movie? That is a storm of energetic protons striking SOHO's digital camera. The protons were accelerated toward Earth by shockwaves at the leading edge of the CME.

SOLAR RADIO BURST AND RADIO BLACKOUT: Last Wednesday, March 30th, the sun did two seemingly contradictory things at once. It produced a loud radio burst and, at the same time, caused a deep radio blackout. Both were side-effects of an X1.3-class solar flare. First, let's listen to the radio burst:

The gentle roar of static you just heard emerged from the loudspeaker of a shortwave radio receiver in New Mexico. Amateur astronomer Thomas Ashcraft recorded it. "The sun was well positioned in my radio antennas for the X1.3 solar flare," says Ashcraft. "The left channel of the audio file is 22.2 MHz, the right channel is 21.1 MHz."

This is a Type II solar radio burst. Shock waves from the flare rippled through the sun's atmosphere, creating plasma oscillations that emit shortwave static. Briefly, the sun turned itself into a natural radio transmitter.

While the sun was busy creating radio waves, it was equally busy wiping them out. Radiation from the flare ionized the top of Earth's atmosphere, preventing terrestrial radio stations from bouncing their signals over the horizon as usual. This map shows where manmade signals suddenly faded:

Ashcraft's observatory in New Mexico is located near the middle of the blackout zone. Take another look at his dynamic spectrum. Horizontal lines are terrestrial radio stations. They vanished for about 10 minutes around the time of the flare. The effect is strongest at frequencies below ~20 MHz.

In Gainesville, Florida, radio astronomer Francisco Reyes recorded the blackout as well. "I used an array of 4 dipoles with an FSX-7 radio spectrograph (Radio JOVE)," he says.

GEOMAGNETIC STORM WATCH (G1-CLASS): A minor geomagnetic storm is possible this week in response to a pair of approaching CMEs. The first CME, launched by an M4-class flare from departing sunspot AR2975, could graze Earth's magnetic field on April 6th. The second CME, flung away from the sun by an exploding filament of magnetism (described below), might deliver a glancing blow on April 7th. Their combined effect could produce G1-class storming. Aurora alerts: SMS Text

A 'CANYON OF FIRE' JUST OPENED ON THE SUN: Yesterday, April 3rd, a filament of magnetism whipsawed out of the sun's atmosphere. On the way out it carved a gigantic canyon of fire. NASA's Solar Dynamics Observatory recorded the eruption:

https://spaceweather.com/images2022/03apr22/cof_anim_strip_opt.gif

The glowing walls of the canyon are at least 20,000 km high and 10 times as long. They trace the channel where the filament (R.I.P.) was previously suspended by magnetic forces inside the sun's atmosphere.

A coronal mass ejection (CME) has since emerged from the blast site. Here it is. The expanding cloud will probably sideswipe Earth's magnetic field on April 7th.

That's why they wouldn't let planes fly. Planes use and depend on satellites for their GPS.. flight plans..and controlling their planes. The sun flares interpret everything...if they went up..planes couldn't fly..they'd crash. So they ground everything. I hope this answers your questions if you were wondering.

SURPRISE GEOMAGNETIC STORM: Earth's magnetic field was supposed to be quiet on April 10th. Instead a strong (G3-class) geomagnetic storm broke out. At the apex of the disturbance, auroras crossed the Canadian border into multiple northern-tier US states. Ron Risman sends this time-lapse movie from Milton, New Hampshire:

https://youtu.be/1Doq_ticqps

"We don’t get to see the aurora all that often in New Hampshire, but this solar cycle so far has been fantastic," says Risman. Before the show was over, the lights spread west through Wisconsin all the way to Washington state.

What caused the storm? The prime suspect is a "canyon of fire" CME, which hit Earth's magnetic field two days ago. Initially the weak impact on April 8th had little effect, but unrest has been brewing ever since. We could be seeing the effect of Earth's passage through the CME's extended wake, which contained unexpectedly strong magnetic fields. A minor solar wind stream arriving during the early hours of April 10th may have helped, too.

The storm is over now. NOAA forecasters say it could flare up again, albeit as a lesser G1-class storm, if Earth encounters another region of strong magnetism ("negative BsubZ") on our way out of the CME's wake.

SCRAMBLED RADIO TRANSMISSIONS: Yesterday's strong geomagnetic storm scrambled HF radio transmissions in North America. Jim Falls (K6FWT) of Eureka, CA, reports: "When the geomagnetic storm alert arrived, I went out to my Ham Shack and listened to Morse code and digital signals in the 80 meter band fighting their way through the storm. They have a particular warbly sound distinctive of trans-aurora propagation; some say it sounds like it's bubbling up through water. Very cool!" Next time, Fall says, he will make a recording for us. Stay tuned.

DEAD SUNSPOT EXPLODES (UPDATED): The corpse of old sunspot AR2987 exploded today, April 11th, hurling debris directly toward Earth. NASA's Solar Dynamics Observatory recorded the eruption:

SpaceWeather updates - Page 4 S_explosion_strip_opt

The S-shaped magnetic filament at the base of the explosion is a classic "sigmoid structure." Solar magnetic fields often assume this shape just before they explode. One study shows that sigmoid precursors are present in over 50% of CMEs.

Indeed, shortly after the explosion, a full-halo CME emerged from the blast site. Here it is. The CME is expected to reach Earth on April 14th; a new NOAA model pinpoints its arrival time at 1100 UTC. The impact could spark a G2-class geomagnetic storm.

SpaceWeather updates - Page 4 Steve_strip

STEVE APPEARS DURING GEOMAGNETIC STORM: A surprise geomagnetic storm on April 10th sparked auroras across Canada and many northern-tier US states. Upon closer inspection, not all the lights were auroras. "STEVE was there, too," reports Harlan Thomas, who sends this picture from Station Flats in Alberta, Canada:

STEVE (Strong Thermal Emission Velocity Enhancement) is a purple band of light that appears during some geomagnetic storms. It looks like an aurora, but it is not. The purple glow is caused by hot (3000°C) ribbons of gas flowing through Earth’s magnetosphere at speeds exceeding 6 km/s (13,000 mph).

"This was the brightest STEVE that I have seen," says Thomas. "It was so bright it overcame a 22-degree halo around the moon!"

GEOMAGNETIC STORM WATCH (G2-CLASS): A CME is heading for Earth, propelled by the unexpected eruption of dead sunspot AR2987. NOAA forecasters say that G2-class geomagnetic storms are possible when the CME arrives midday on April 14th. During such storms, auroras can seen as far south as, e.g., New York and Idaho (geomagnetic latitude 55 degrees). Aurora alerts: SMS Text

FARSIDE EXPLOSION TARGETS MERCURY: A coronal mass ejection (CME) flew away from the farside of the sun during the late hours of April 11th. A new NASA model shows it is going to hit Mercury. Note the orange dot in this forecast animation:

SpaceWeather updates - Page 4 Nasamodel_strip

https://spaceweather.com/images2022/12apr22/nasamodel_strip.gif

If the CME overwhelms Mercury's relatively weak magnetic field, it could scour material off the planet's surface creating a temporary atmosphere and adding material to Mercury's comet-like tail.

The farside of the sun has been active this week, with more than one significant CME. Helioseismic soundings of the farside reveal a large region of intense magnetism--probably a complex sunspot group. It will rotate over the sun's eastern limb about a week from now.
