Sam Warfel Posted December 28, 2021 Share Posted December 28, 2021 Bit of a surprise activity, AR2918 is in the process of emitting an M1 flare. Ā It appears to be long-duration as well. A CME to follow, perhaps? We were all focused on 2916, but 2918 has usurped the stage! Link to comment Share on other sites More sharing options...

AR2916 finally woke up", but turns out it isn't! It's not dead center on Earth but I bet this could still be geoeffective if any CMEs are launched.

Solarflaretracker200 Posted December 28, 2021 Share Posted December 28, 2021 Looks like it may be a long duration flare.Ā Link to comment Share on other sites More sharing options...
Flareguy18 Posted December 28, 2021 Share Posted December 28, 2021 No radio emission alerts from SWPC as of yet, but that doesn't always mean no CME. Fingers crossed we see something in LASCO! Link to comment Share on other sites More sharing options...
Solarflaretracker200 Posted December 28, 2021 Share Posted December 28, 2021 Sadly I missed the flare, but by looking at it, it may be a long duration. Or am I wrong?Ā Link to comment Share on other sites More sharing options...

Drax Spacex Posted December 28, 2021 Share Posted December 28, 2021 (edited) This would make an interesting case to examine in slow motion given the percolating C flares 4 hours earlier from this region.Ā From this burgeoning activity, one could have perhaps predicted a strong flare was imminent.Ā Ā Some large coronal loops in the region and north-extending filament(s) appeared to be interacting as well.Ā ah-aH-CHOOO!

Vancanneyt Sander Posted December 28, 2021 Share Posted December 28, 2021 Coronal dimming was low, maybe a little fluffy cloud but not worth speaking of. Ā Link to comment Share on other sites More sharing options...
Solarflaretracker200 Posted December 28, 2021 Share Posted December 28, 2021 (edited) So no CME? If this is right, then a CME has to be from a long duration flare? (Who knows if that's right because I just read that off the internet while searching something up.) I think AR 2918 is making a M class right nowĀ Edited December 28, 2021 by Solarflaretracker200 Link to comment Share on other sites More sharing options...

I think AR 2918 is making a M class right nowĀ A CME does not have to originate from a long duration flare, but in general long duration events are more likely to produce a CME than an impulsive event. It does appear AR2918 just flared again, but this one looks more impulsive than the M-flare several hours ago. No CME was produced with the earlier activity.

Christopher S. Posted December 28, 2021 Share Posted December 28, 2021 Based on surroundings and my visual analysis of the plasma density around 2918, it's gonna take at least an M-flare or a C-flare that jumbles its configuration up a bit to get a good CME out of it. 1 Link to comment Share on other sites More sharing options...

NightOwl Posted December 28, 2021 Share Posted December 28, 2021 How can you tell if there is coronal dimming after a flare? I've seen this term a lot but haven't been able to figure out what to look for. Link to comment Share on other sites More sharing options...

You can find it here:Ā https://wwwbis.sidc.be/solardemon/dimmings.php as the term indicates, it is literally dimming of the solar corona š hence the name coronal dimming. 1 1 Link to comment Share on other sites More sharing options...
