CME WATCH - 2023.04.07: The string of CMEs off the SE limb continues. The bright streamer off the SW limb brightened and partially erupted as predicted - looks like its getting ready to go again. Also the bright streamer off the NW erupted too. Busy night!

THE SUN TODAY:

1) SNN up to 45 and area to 300 mil.

2) An M3 flare plus a couple of mid-level C flares, all from AR3272.

3) NE limb promising a new region but only scattered plage so far.

4) Note all the activity is in the southern hemisphere. Some big prominences around the limb

CME WATCH - 2023.04.08: The bright streamer off the SW limb brightens and produces a large, slow CME. The bright streamer just west the N pole produced a small CME, then a very impressive one and by the end the streamer is gone. A few modest CMEs off the east limb towards the end

CME WATCH - 2023.04.09: A lot of missing data Sad

. We start with 3 strong CMEs one after another: one off the southwest, followed by a bigger one off the east limb and a very large one off the northwest. Finally, one off the southwest. Note Jupiter sneaking in from the southeast.

THE SUN TODAY:

1) SSN up to 75, area 330 mil.

2) M3 and C6 flares earlier the morning both from the new region on the SE limb.

3) More activity to come from behind the southeast limb.

4) Two other regions emerged both in the north (white). The one on the NE limb is a large spot.

PROMINENCE / FILAMENT ERUPTION: A prominence sat happily on the limb for hours, then started to rise and be dynamic. Then it erupted in two parts: one violently on the disk (the filament) and a much larger one that stretched over the far limb (the prominence).

Worth clicking on the link and viewing the little movie.

THIS WHY THEY CALL THEM ACTIVE REGIONS: A new sunspot region is rotating on to the visible disk over the SE limb of the Sun. Not all the busy activity from the region. It has already produced M3 and C6 flares (see earlier tweets) - expect more.

A CLASSIC SLOW FILAMENT ERUPTION: You can see the dark filament start to rise and accelerate away from the Sun but note that much later a large amount of plasma falls back onto the Sun's surface in the southern part of the region. I don't see any impact brightening when it falls.

Fantastic video, worth a look.

CME WATCH - 2023.04.12: Jupiter exiting stage right. Almost looks as if the Sun is trying to hit with CMEs but, of course that is just a perspective effect. Jupiter is 100s of millions of km away. Most CME activity is off the W limb, though most of the activity has been on the E.

NEW SUNSPOTS APPEARING: A series of spots are appearing over the SE limb. Note the leading region is a simple, stable spot so likely the remnants of an old region. A larger region following has big spots but too early to see their dynamics. A 3rd region just appearing to the east

https://twitter.com/i/status/1646324984191623168

The above can help you understand sunspots.
