MeteoLatvia Posted February 25 Share Posted February 25 (edited) Looks like a long-duration flare now onset. Just looked at GOES SUVI and this flare at first glance looks eruptive - bright material moving in the southern part as many of you already said.

Are they connected in some way? I see a pretty decent CME leaving the northwest region but already on LASCO C2 so curious what caused that CME 🤷♂️🤷♂️ Link to comment Share on other sites More sharing options...

Agree, doesn't look impressive, I'm just glad we have some M-flare activity again, been like 30 hours since last one 😅 4 2 Link to comment Share on other sites More sharing options...

Aten Posted February 25 Share Posted February 25 5 minutes ago, MinYoongi said: why? 😕 Oh Because the flare is near the center of the sun, big CMEs only happen on the limb. But seriously, the coronal dimming in in the SUVI images looks pretty minor. Just because there is some slight dimming does not mean there will be a substantial CME. There was some slight dimming following the X6 flare too, but I couldn't see any CME in the coronagraph images. 1 1 Link to comment Share on other sites More sharing options...
MeteoLatvia Posted February 25 Share Posted February 25 Does long-duration flares almost guarantee CME, or it is just one of many indicators of possible CME? Link to comment Share on other sites More sharing options...
Ingolf Posted February 25 Author Share Posted February 25 In SDO AIA 94 from 17:35 UT is something flying east of 3590. Is this an artifact or something real? Link to comment Share on other sites More sharing options...

Are they connected in some way? I've been keeping track of simultaneous flares or 'sympathetic flaring' and I'm fairly certain it happens when a regions boundary line is in close proximity to another and/or a filament connects two boundaries. I made a rough example with this current flare and drew a line through the filament in 171-304aia region to region. Lastly I used SWPC synoptic map and drew in the same filament channel over the depicted boundary lines. 5 Link to comment Share on other sites More sharing options...

willow Posted February 25 Share Posted February 25 the last flare seemed to have some potential for a small CME. Really interesting region both for it's complexity and, probably, strong magnetic cage that doesn't let anything out Link to comment Share on other sites More sharing options...
Jesterface23 Posted February 25 Share Posted February 25 (edited) Negative polarity spots keep back-building south of the positive polarity spot and that seems to be what's keeping the region active Edited February 25 by Jesterface23 2 Link to comment Share on other sites More sharing options...
