There was a huge X-class solar flare yesterday on the Sun!

You can see it on the right-hand limb in these SDO images.

I find it so neat that we live next to, and can study, a star.

We take it for granted that it's "the Sun" and it's always in the sky, but there is a star and it is RIGHT THERE.

SDO's different filters allow us to look at different wavelengths of light which describe different regions, processes and temperatures of the solar environment.

Science is rad, hey. We have a close up view, and are looking at a star.

An X1.2 flare peaked at 15h40 UT 13 May. A major R3 radio blackout affected the western Atlantic and Caribbean regions. The flare originated form AR4079 which is almost on the west limb. A large CME has been observed heading to the west.

Type II and 10cm radio bursts have been observed.

My best pictures from the May 2024 #aurora storm were from Memaloose State Park near Mosier, Oregon (1 hr east of Portland on I-84), overlooking the Columbia River and getting some #AuroraBorealis reflection in the water. It was only the 2nd time I had seen aurora, and first time from the ground. It was a lot better than out a 767 window with stone-age camera tech of 2003. spacey.space/@AstroHawk/112421 #AuroraBorealis #astronomy #SpaceWeather

Mountains across the river are in Washington state. (edit: For scale, the Columbia River is 3/4mi or 1km wide at this point.) #astronomy #SpaceWeather

Hard to believe it's been a year since the G5 (Kp=9+) geomagnetic storm that brought #AuroraBorealis down to Oregon and beyond. I got pictures of Multnomah Falls with red #aurora behind it, which is looking south. We should normally not see polar lights to the south at 45.5N. spacey.space/@AstroHawk/112421 #AuroraBorealis #astronomy #SpaceWeather

Spacey SpaceAstro Hawk (Ian Kluft) 🚀🛰️ (@AstroHawk@spacey.space)Attached: 2 images I got a pic of Multnomah Falls (east of Portland OR) with red aurora behind it - this is looking south. You know it's big when polar lights are south from here! (edit: It was dark so I goofed selecting the image. I added the pic of the falls, but the other was also taken there.) #AuroraBorealis #astronomy #SpaceWeather

The sun is back to "rather dull" mode. The XRay flux has not risen above C4.7 in the last 36 hours. The large active region AR4079 is largely unchanged and is not doing much flare-wise.

Meanwhile a minor geomagnetic storm level G1 is in progress. A G1 storm watch is in effect for 24 hours from midnight (UT) tonight.

Ooh, hello? New Active Region AR4079 is starting to look more interesting.

The sunspot group is currently classed as a Beta with a 35% chance of producing an M-flare and 5% chance of an X-flare in the next 24 hours. It did already produce an M1.7 flare at 05h13 UT this morning.

There's currently an interesting loop of material visible on SDO (AIA 94 filter - first image).
