Two differing views of tonight’s ongoing long-duration #SolarFlare, which sat for nearly 4 hours above M-class levels. It appears that an initial filament eruption triggered a much larger event! #spaceweather (data: AIA/SUVI/LASCO)

Yesterday the Sun produced this moderate-class #SolarFlare. Despite its smaller size, it was a long duration event, continuing for several hours and providing this hypnotic view of beautiful coronal rain (seen in yellow) and Supra-arcade Downflows (seen in cyan). Mesmerising!

The second of today’s X-class solar flares was truly a long-duration event. Where typical flares last 10s of minutes, this event took over 6 hours. The flare also showed a fundamental part of solar flares: a ‘current sheet’. #spaceweather 1/5

.NOAA's #SpaceWeather Prediction Center has issued a G3 (Strong) Geomagnetic Storm Watch for April 16, after a coronal mass ejection (#CME) erupted from the sun last Sunday. The Solar Ultraviolet Imager (#SUVI) onboard NOAA's #GOESEast 🛰️ captured the Earth-directed double filament eruption. NOAA Space Weather Prediction Center #GOES19

AR4274 remains highly active. A long-duration M4.7 flare was followed by a filament-triggered X4.0 flare, producing two CMEs. 1st CME is directed toward the northwest, and the X4.0 event generated a full-halo CME with possible Earth-directed component.

Last night’s moderate #SolarFlare likely released more energy than the majority of larger X-class events. Why? Flare classifications are determined by the flare’s *peak* emission. Although last night’s flare capped at an M3 level, it continued releasing energy for over 12 hours!

Two fast plasma filament destabilizations which both produced canyons of fire afterwards, especially the larger second one at the end.

The sun had four dramatic filament eruptions over the last 24 hours, and the Solar Ultraviolet Imager (#SUVI) onboard NOAA’s #GOESEast 🛰️ caught them! These filaments are comprised of long strands of cooler, denser plasma that lift off the sun’s surface. #GOES19

Today (02/02/26 UTC) we had one of the strongest solar flares of the 21st century, a combined 8.1, 1.5, and 2.8 x-class solar flare sequence that is still ongoing at m-class levels. FLASHING LIGHT WARNING FOR SENSITIVE VIEWERS.

The volatility - yes, volatility - in AR 4366 is absolutely unbelievable. I don't think I have ever used the word 'volatility' to describe an active region. The X-ray flux has been mostly above the M-class threshold for *35 hours* now. There have been 25+ M-class and 4 X-class flares. It is unfortunate that most of these flares are impulsive, else we'd have a train of CMEs en route and likely impacting by now. Even so, the show is incredible, one of the highlights of Solar Cycle 25 - we will be talking about this for a long time!

The latest X8.1 flare was eruptive you might have expected. It was a big filament (cool material) eruption. It was also seen as a coronal wave. We need to wait for more coronagraph data to say if/when the associated CME will arrive, but it will probably on Feb 4.

Episode 47 of Kilauea’s ongoing eruption began a few hours ago. She never disappoints. What a stunner 😍

Spectacular eruption accompanied the X1.9 flare. Its shock wave set off a nearby filament and even triggered a behind the limb eruption. Dimming spread across the geoeffective zone. This region enters Earth-facing view next week and needs close monitoring.

the long lost "Scotsman Cut" of TATMR has a rumored runtime of nearly 4 hours, and this is the only surviving clip of it today

The X1.9 flare is strongly eruptive, triggering a nearby filament eruption. Widespread dimming accompanied the event, and launched a fast, Earth-directed full-halo CME.

🚨 Massive eruption just blasted off the Sun — Oct 21, 2025 | 20:36 UTC. This was a major solar event with a possible Earth-directed component. Too early to confirm, but early data shows it’s big. More updates soon. ☀️ #MrMBB333 #SolarStorm #SpaceWeather

In NY City, it appears there are two levels of justice. The police aid their buddies to skip buying a ticket for the subway.

Thursday’s X9 #SolarFlare was captured by the NASA IRIS mission! IRIS observes the Sun with much higher resolution than the flare images you typically see, but over a small region. It can also observe the flare core without saturating the images! #astronomy #spaceweather

A singer in revealing clothing appears at an Entertainment Authority event in Jeddah… Scenes that have begun to repeat recently in #SaudiArabia, contradicting the identity and traditions of a society long known for modesty and dignity.
