CME WATCH - 2023.03.02: Forgot to post this last night - sorry. Classic slow CME off the southeast limb near the end of the video, shortly followed by one off the NW. Connected - unlikely.

You can see what a CME (Coronal Mass Ejection) does in the video in the link above.

Sorry—can’t post the videos directly, the format is not supported by this board.

THE SUN TODAY:
1) SSN up to 120.
2) X2 flare from AR3234 (see previous tweets) and an M1 from AR3243.
3) Helioseismology shows large areas of magnetic disturbance on the far side of the Sun but how much of it is plage or sunspots?
4) Most Regions seem stable.
5) 13 CMEs yesterday

A GROWING SUNSPOT REGION: Many violent eruptions from this new sunspot region near the northeast limb. As new magnetic field emerges from below the surface of the Sun it interacts with the existing fields causing flares. I guess that is why they are often called Active Regions!

Three nice "bubble" CMEs off the west (right) limb. Two slow-mo CME's off the SE and east limbs respectively. https://twitter.com/i/status/1632196575505047554

AR3234 may have set over the west limb but still producing flares. The real intensity is probably much larger. 5) 10 CMEs yesterday

Developments today:

M FLARE! A very impulsive M5 flare just occurred near the NW limb in sunspot region AR3243 peaking at 21:36 UT. The large loops in the background over the west limb are the impressive structures of AR3234 that gave us so many big flares.

CME WATCH - 2023.03.05: We start with a very spectacular CME off the W limb - could it affect the Earth? Possibly in a day or so. Another thin bright CME off the SE limb adjacent to the bright streamer. Then a fainter one off the west limb again (the M flare - see earlier tweet).

THE SUN TODAY:
1) SSN soars to over 200, for only the second time this cycle.
2) Five M flares in last day.
3) New region coming over the SE limb.
4) The M flares came from four different regions. Lots of tiny spot regions emerging - will they amount to anything?
5) Only 4 CMEs.

Over 200 sunspots!

THE SUN TODAY:
1) SNN drops as some regions set over west limb.
2) One M flare and a few Cs. Two newly numbered sunspot regions: AR3247 / 48.
3) More regions behind both NE and SE limbs.
4) The M flare was from AR3242; the 3 C flares from scattered regions.
5) 8 CMEs yesterday.

SSN should increase soon as the new regions come into view.

THE SUN TODAY 2023.03.07: Some spectacular events early on, then a long quiet patch followed by a violent eruption off the northwest limb (upper right).

DOUBLE TROUBLE: The cause of the violent coronal mass ejection (see last tweet) is now clear here. There is a filament eruption in the southern part of the region followed by a second, smaller one further north. Note the size of the event compared to the Earth (top left corner).

THE SUN TODAY:
1) SSN down again to 150.
2) Just had an M1 flare from sunspot group AR3242, otherwise all's quiet.
3) New region behind NE limb.
4) New sunspot group coming over NE limb does not look strong. Lots of small regions popping up briefly.
5) Only six CMEs yesterday.

Seems like lots of fluctuations, burst of energy (sunspots, flares, CMEs) then sunspot number etc reduce for a while.

Some fools still wedded to the idea of a GSM now marked the first retreat from 200+ spots as the peak. Nope, peak is in later half of 2025, still 2 years to go to the peak of SC25! This is ideology trying to trump observation, willing the sun to reduce the number of spots. Fluctuations don’t matter.

Not that SC25, the current Solar Cycle, is going to have 1000 sunspots at peak or anything like that. The number of spots, flares & CMEs will be higher than at the peak of SC24 is all. Maybe 300 sunspots at peak? (SA24 had 220 spots at peak.)
