chronical Posted May 2 Share Posted May 2 (edited) AR 3663 is becoming more and more interesting everyday. The previous run shows two opposite polarities right next to each other. With HMIIF, I can see that there might be a penumbra share, but not an umbra share (yet). I would quite probably keep my eyes on that sunspot in the days to come.

mozy Posted May 2 Share Posted May 2 Certainly capable of producing bigger flaring now within that spot. 2 Link to comment Share on other sites More sharing options...

It's quite compact and is fairly sizeable with more spots growing into it. Definitely looks good for bigger flaring with this growth. 3 1 Link to comment Share on other sites More sharing options...

Im not quite getting it.. 😧 On some occasions for delta spots when seen on the intensitygrams it seems like not just their penumbrae are merged, but that even the umbrae themselves are merged, i.e. looking like a single umbra despite having two different polarities. But yeah, in this case it's just a regular delta as far as I can tell, but it looks fairly good, decent-sized spots very close together and fast growth, so we'll see how it develops. 2 1 Link to comment Share on other sites More sharing options...

When did it start developing in that good direction? so i can pull the right pictures from sdo, since movies still are a pain on apple. 1 minute ago, Philalethes said: On some occasions for delta spots when seen on the intensitygrams it seems like not just their penumbrae are merged, but that even the umbrae themselves are merged, i.e. looking like a single umbra despite having two different polarities.

I now understand! Yeah they are not that "mushed together" yet, as youve said earlier. thats why i said it looks like a "normal delta" to me. when did it start developing? I sadly was quite busy in the last few days so i did not catch it Link to comment Share on other sites More sharing options...

Probably late yesterday at some point, I only have pictures of it locally from around 02:00 today. From then it developed like this: 1 minute ago, MinYoongi said: im gmt+7 i believe.

The delta looks pretty good, I'd also be expecting some flaring from it. I’ve always thought that a delta had to have a merged umbra, thanks for correcting me @Philalethes, I wonder if you have access to the data that indicates if this sunspot group is magnetically caged or not? Or is it evident that it is not caged because, compared to the two recent cases, the sunspot group is smaller ? Edited May 2 by chronical Link to comment Share on other sites More sharing options...

Jay-B Posted May 2 Share Posted May 2 Does a sunspot with a delta have to go a period of time without releasing smaller flares in order to release an x-flare or does it just increase its probability of it happening? Link to comment Share on other sites More sharing options...

It definitely varies with every sunspot, some are just quiet while other regions produce X-flares only after smaller flares trigger it, some are letting off steam constantly killing the delta before anything bigger can happen. 1 Link to comment Share on other sites More sharing options...

Jesterface23 Posted May 3 Share Posted May 3 It seemed to be a somewhat eruptive event across the northern and southeast disk. Center and west-center disk CHs would be blocking the shock there. ........ Early info, STEREO A is the first to capture the CME in coronagraph imagery. 1 Link to comment Share on other sites More sharing options...
