Massive solar storm causes communications blackouts

The strongest solar flare so far this year hurled streams of plasma and charged particles into the cosmos and Earth's atmosphere Wednesday morning.

The sun unleashed two huge flares early Wednesday, one day after a NASA observatory captured a dramatic photo of a separate solar flare.

The back-to-back eruptions included the strongest of the year so far, and have reportedly caused shortwave radio blackouts on at least five continents. The outbursts this week may be signaling that the sun is ramping up its activity. #spaceweather #solarstorm

Well the sun has really woken up from a slumber during the last 24 hours!

Flare | Peak time | AR#
X1.2 15h36 UT 13 May AR4086
M5.3 03h20 UT 14 May AR4087
X2.7 08h25 UT 14 May AR4087

Active region AR4087 is the new player in town punching an X2.7, just as AR4086 on the opposite side rotates over the west limb following its X1.2. A CME was observed from the X2.7, along with a 10cm radio burst.

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

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).

Activity is still officially "boring", but are things about to change?

The farside monitor shows that the mysterious blob (an area of magnetic activity) will soon be appearing over the east limb. Huge magnetic loops above the limb are suggesting something interesting is coming!
