Arrived!
The anticipated CME (CME-driven shock wave) has arrived (~04:25 06/05/2026). Congrats to those forecasters whose predictions were accurate to less than a few hours.
The magnetic field is presently northward. Can you predict how it evolves over the next 12 hours?
Direct Hit! The solar storm launched during the M9.3-flare is indeed Earth-directed! Since this is the second significant eruption from Region 4455 while in the Earth-strike zone, this means this second storm could get "held up" in "traffic" on its way to Earth. The NASA solar storm prediction shows the second storm arrival by late June 4. However, the first storm will precede this so expect some impact starting around mid-day June 4 with the stronger storm arriving close behind!
Reports of an explosion hears around Boston I believe are going to be a rather significant bolide/meteor entering the atmosphere. Very large "flash" detected by GOES-19 GLM that does not correlate with active thunderstorms. #MAwx
Today's solar eruption associated with an M1.9 flare in AR 14436. The coronal wave does not look like strongly driven in low altitudes; no type II radio burst in NOAA's report. But the eruption may be strong higher up. There is a chance of glancing Earth during 19-20 May.
The fast solar wind is now giving us sustained southward field so aurora is dropping down to mid-latitudes now! Although the Ovation model was overestimating aurora viewing earlier today, that is no longer the case. Expect views to continue to brighten over the next several hours at least. The new moon tonight also means skies should be exceptionally dark! Perfect for viewing where skies are clear!
Here is a unique view of a solar flare, captured by the NASA IRIS space telescope last month. We’re used to seeing ‘saturated’ images of flares, but this movie shows an unsaturated view of solar flare heating and plasma motions in the lower solar atmosphere!
The eruption on 10 May 2026 from AR 14436 (associated with an M5.7 flare) was spectacular enough to wake me up. The region is the target of a Major Flare Watch by the Max Millennium Chief Observer.
The aurora started as a faint glow on the horizon as daylight dropped. Then the pillars went up and the whole southern sky turned violet/magenta. The Milky Way was already there, just waiting for someone to notice. The evening was so calm you could hear a pin drop on the crusted lake.
