Sunspot region 2860

Region 2860 has developed quite nicely in the past 24 hours and produced its first M-class solar flare! M4,7 with an earthward directed CME. We await LASCO imagery for more details. 

 it’s worth noting the region has a strong delta spot in the center squished to a spot of opposite polarity. More strong solar flares are likely. Exciting times ahead!

Very nice to finally have some solar action again but the resulting CME looks very disappointing coming from such a nice flare...

Im amazed at how fast you are feeding us with info, given its only midday in Europe and the flare just happened. Love you for that!

 

So, as Im a noob at reading Lasco properly since this is my first Cycle observing properly, how do you determine that it is dissapointing? Is it faint/diffuse? Not fast? Not a direct hit?

Thanks! We are based in Europe as well so looking at LASCO and STEREO fits right into the ''before lunch'' time slot. :D

I just look at STEREO COR2 and SOHO/LASCO imagery in motion. After looking at CMEs for years you quickly see which ones are interesting (fast/dense/well aimed at Earth) and which aren't.

Here is another image from LASCO, it really does not look good. It is just really faint and slow.

Here you have an example from July 2000 of how I want a CME to look like :D

Indeed.  The region is still quite fussy.  The magnetogram of 2860 looks like a Jackson Pollock painting - a splattered mess.  The latest, an impulsive C8.13 "Captain Hook" flare at 2021-08-29 10:03.

The wide black band along the equator (AIA 211) - is that a coronal opening producing a solar wind?  Could that cause any ejecta (my new favorite word) to be blown north or south of the solar equatorial plane, deflecting it away from Earth?

Yeah, and 14 flares in 48 hours.. very cool little (gigantic) paint splotches indeed.
