National Geographic photographer Paul John Bayfield photographed the recent solar eclipse with a herring gull from over Norwich, UK. A moment he described as "a sight I shall remember for a long time.”

Mars took such a battering from the same active region a week after us. Bet you're regretting not having an intrinsic magnetic field now, eh, dusty red cousin?

Yesterday’s near X-class #SolarFlare (M9.75-class) produced a clear CME and solar radiation storm (causing the fuzzy noise shown in the data). The CME is expected to arrive Monday, with a G2 geomagnetic storm currently predicted. #spaceweather #astronomy

[Keith Strong @drkstrong]

Note how the proton storm starts soon after the CME is seen from the west limb. That means that the particles are traveling at near the speed of light - i.e., they have been accelerated to relativistic speeds by the flare.

Another angle of that whopping storm...

🧲 The view at the top shows the massive strengthening of Earth's magnetic field at the poles!

Did any of you capture the aurora last night? Some of our colleagues did. It was caused by several major flares and filament eruptions as observed by NSF GONG earlier this week.

Geomagnetic activity has been calming for the past three hours, but we don’t expect things to be done yet. There are still further solar eruptions en route, which could result in auroral conditions picking up again! #spaceweather #northernlights

Nature is full of wonders. The feeling of experiencing one of them is unparalleled, especially when you study it and analyze its causes. The Aurora is one of the marvelous phenomena that captured my heart ...

Extreme (G5) geomagnetic conditions have been observed!

A G4 (Severe) Geomagnetic Watch has been issued for May 11...

[Industrial Engineer Irene Quiroz @nenecallas]

Wow, the earth will definitely be impacted by multiple CME's is observed in the ZEUS simulation.

[SolarHam @SolarHam]

Strong G4 storm watch in effect for this weekend. Also the latest X-Flare measured X1.1 and looks to be the source of yet another CME. More to follow.

[Austrian Space Weather Office, GeoSphere Austria @ASWOGeoSphere]

With our (experimental) ELEvo model we get CME arrivals at Earth starting Friday May 10 at 16 UT +/- 7 hours, arrival speeds 600-900 km/s.
All CMEs in DONKI are shown. The 4 halo CMEs are the wide and fast ones towards Earth on May 8/9. Others go to high/low latitudes.

A moderate G2 geomagnetic storm watch has been issued for this Monday and Tuesday by the NOAA SWPC. This is due to the anticipated arrival of a coronal mass ejection launched yesterday morning from an eruption near sunspot region 3557. High and upper middle latitude sky watchers should be alert for possible aurora displays in the next 24 to 72 hours.

[Dr. Ryan French @RyanJFrench]

2023 was a busy year on the Sun (and as a result, a busy year for my account!). This thread contains my favourite highlights of all the extreme-UV solar observations I posted this year. Combined, giving over 10 minutes of #SolarFlares, eruptions, and more! 1/8

The X5.0 solar flare from sunspot region 3536 is the strongest solar flare since Sep. 2017. The resulting coronal mass ejection is impressive but based on the latest LASCO imagery and the location of the eruption, unlikely to impact Earth.
