Jesterface23 Posted April 15 Share Posted April 15 @Wolf star If you want to, you can rename the topic with 3637, 3638, 3643 cluster. Seeing the HMI imagery now, I think it very well reasonable. 2 Link to comment Share on other sites More sharing options...

Philalethes Posted April 16 Share Posted April 16 Seems to be some complexity emerging around 3637 and 3638 lately. 2 Link to comment Share on other sites More sharing options...
Jay-B Posted April 16 Share Posted April 16 This delta has been there for 2 or 3 days and is still not classified yet. I wonder why? 4 Link to comment Share on other sites More sharing options...

We had a case like this last year also where it looked like there was a lot of impingement or whatever. The lack of activity made us all wonder too. I wonder how active in C level flaring this AR is. 1 Link to comment Share on other sites More sharing options...
hamateur 1953 Posted April 17 Share Posted April 17 (edited) Interesting. Solar Ham lists 3637 as currently a BD. @Jay-B I wonder if SWPC is “ dividing” up these ARs in a similar manner to the four Northern Hemisphere regions earlier this year, I haven’t checked the synoptic map and will have a look I think. It’s hard for me to tell exactly where they split it, but the delta looks active in latest 131 angstrom shot of 3637. And SFI should stay in the 200 range. North limb looks good too! Part of the problem being that our background flux is low to mid C level and many smaller flares are perhaps not registered. Jan ( Solen) agrees apparently and thinks it capable of further M flares. Good catch. Mike Edited April 17 by hamateur 1953 Delta 1 Link to comment Share on other sites More sharing options...
Parabolic Posted April 17 Share Posted April 17 Looks like AR3638 has began ejecting a few CME's. So far the strongest CME associated flare has reached C9.0. Hopefully the coronagraph will show something promising as this group of AR's continues to evolve. Link to comment Share on other sites More sharing options...
Parabolic Posted April 18 Share Posted April 18 AR3643 is now flaring as well. 10.7cm is at 215+/- so I'm betting the light show is about to begin 🙂 1 Link to comment Share on other sites More sharing options...

AndrewB Posted April 18 Share Posted April 18 (edited) After M2.2 from AR3643 peaked at 0248Z we have a CME visible via COR2A and C2. Not large and mostly south but maybe will bring us some activity in 2-3 days. Edited April 18 by AndrewB 2 Link to comment Share on other sites More sharing options...

I certainly agree and would be very pleased to see 250 sfi tomorrow or Friday. Honestly, I kinda expected a resurgence in activity after the recent lull, but 100 SFI in under two weeks was nice! 1 Link to comment Share on other sites More sharing options...

Cool @Wolf star it would be cool is ya had a wife named Rayet. Haven’t checked your profile though.. hopefully ya ain’t offended Wolf-Rayet are really unusual stars btw. I mistakenly thought they were two stars locked in a spiral but maybe not! Siily anyway.

Adohran Posted April 18 Share Posted April 18 It appears as if we get another flare from the region. already at C9. Looks like more than the last ones we got. 1 Link to comment Share on other sites More sharing options...

Hopefully it will continue producing solar storms as it makes its way to the western hemisphere 🙂 Link to comment Share on other sites More sharing options...
LunarLights58 Posted April 18 Share Posted April 18 (edited) Pop pop pop pop popping off with this region, might get some deltas even. Edited April 19 by LunarLights58 Link to comment Share on other sites More sharing options...
Philalethes Posted April 18 Share Posted April 18 This one's a bit longer in duration than the other ones lately, but doesn't quite seem eruptive. Link to comment Share on other sites More sharing options...

Is magnetic caging still an issue now in this particular area? This is the third eruption that lasts a bit longer where I see some potential/hint of loops starting to lift but they've all failed to do so.

I did wonder myself earlier, so I dug up the data on the current region, here. The unsigned flux is definitely still high, near the upper end of the range, so could be. So far it seems like it's typically that high for most big regions though, will be interesting to see what it's like if a really complex region pops up. Here's a plot of this one so far: 3 1 Link to comment Share on other sites More sharing options...
LunarLights58 Posted April 19 Share Posted April 19 Region 3647 is a Beta-Delta now, so that's cool. 1 Link to comment Share on other sites More sharing options...
SamDieGurke Posted April 20 Share Posted April 20 looking at 304Å on SUVI it seems like something small and slow got spit out by AR3638 or somewhere near there. Probably nothing noteworthy but just noticed this while looking at it. Link to comment Share on other sites More sharing options...
mozy Posted April 21 Share Posted April 21 (edited) Another long duration flare from this cluster that fails to produce a CME, this whole region/area sucks... Edited April 21 by mozy Link to comment Share on other sites More sharing options...
Jesterface23 Posted April 21 Share Posted April 21 Talk about strength in numbers, there is a single magnetic loop spanning across region 3645, 3647, and 3643. Roughly 25 degrees 2 Link to comment Share on other sites More sharing options...
hamateur 1953 Posted April 21 Share Posted April 21 (edited) That is a big “Magnetic Cage” indeed. wonder if @Parabolic is around? They brought this interesting subject up in emerging flux theory awhile back I think. Although I don’t know if it would apply in this instance. Edit: It sure is hot in 131 ang. Just a little push. Reconnecting and blammo! Our baseline flux is being held halfway up C level now probably by this guy alone.
