Landon Moeller Posted November 11, 2022 Share Posted November 11, 2022 Looks like this region is getting peppy, with very frequent C flares this evening near center disk. Unfortunately this may mean the big flares/CMEs May happen towards the western limb and miss earth, but let’s hope that will not be the case Link to comment Share on other sites More sharing options...

" Region 3141 continued to be in a growth phase and formed a delta in the northernmost area of the Region." I dont really see it. honestly. https://ibb.co/RgXLVsh Link to comment Share on other sites More sharing options...

mozy Posted November 11, 2022 Share Posted November 11, 2022 Yeah I think they're a bit too fast on the ball calling that a delta, but that'll be the area of interest. However, I can see this being called a delta anytime soon. 2 Link to comment Share on other sites More sharing options...
MinYoongi Posted November 11, 2022 Author Share Posted November 11, 2022 M class flare. Seems eruptive but looks 1. Impulsive and 2.southward trajectory to me Link to comment Share on other sites More sharing options...

The Penumbras may touch a little bit but not a delta imo Definitely no delta that I can see either, neither in that image nor currently. Interesting with the flaring, though, just goes to show that it's hard to predict where eruptive activity will be coming from. After all, spots emerge in the first place, so even a region which seems to be dying down can quickly be revived by subsurface activity. Link to comment Share on other sites More sharing options...

Is anyone looking at Stereo? It looks like maybe a CME was launched, in Suvi i dont really know if it looked earth directed. more west/southdirected. Lasco has like 1 Frame of it so far.

Too soon to call, we need more frames of it and to see it on C3. The main part looks to be west, but it’s possible there’s a halo we can’t see yet because it would be the slower part and may not appear on the imagery just yet 1 Link to comment Share on other sites More sharing options...
Jesterface23 Posted November 11, 2022 Share Posted November 11, 2022 There is something dull that is Earth directed from at least the first M-Class flare. What is missed is that the western bright CME in the C2 imagery is a limb CME. 1 Link to comment Share on other sites More sharing options...
Drax Spacex Posted November 11, 2022 Share Posted November 11, 2022 The location of these flares from 3141 is so close to the center disk, CME components along the Sun-Earth vector may be hidden within the LASCO occulting disk which gives a rise to the possibility of undetected stealth CME or "transient effects". 1 Link to comment Share on other sites More sharing options...

There was a Prominence lift off in the western part. 2 minutes ago, Drax Spacex said: The location of these flares from 3141 is so close to the center disk, CME components along the Sun-Earth vector may be hidden within the LASCO occulting disk which gives a rise to the possibility of undetected stealth CME or "transient effects".

Or it might just take longer for them to come into view on LASCO (although you’re quite right, if they’re narrow they may never do so) 1 Link to comment Share on other sites More sharing options...

May i say its really frustrating that we get an SDO update like every 8 hours now.. In the 15:30 Update it doesnt looks as delta'ry anymore.

Drax Spacex Posted November 11, 2022 Share Posted November 11, 2022 A topological feature I have seen as often associated with strong flare activity (a discriminator) is a C-shaped or mirrored C-shape arc of contiguous sunspots or flux surrounding a central region of opposite polarity like a ring of pearls. The latest HMI Magnetogram for AR3141 exhibits this feature. https://ibb.co/StVnFth Might this presage more M-flares (or stronger) to come from this region? 1 Link to comment Share on other sites More sharing options...
