Any of these producing cme?

3599 definitely has what appears to be a textbook delta. Hopefully it continues on its development.  I haven’t looked at latest 131 but it should be improved markedly if I’m not mistaken. 

when did the delta form? i just now started watching this region. at 04UTC it got onl 5% for M-Flares so i suppose it wasnt there then?

in the sdo movie i can see it got stronger since the last 2h.

@Adrian Kobyłecki was the first to announce seeing it about 14 hrs ago. It probably had just begun  to form and began spitting out low C Flares.  As noted it is a clear bgd now.

Yes. C levels only so far but the little delta that could has doubled in size overnight. Good news.

I see something in LASCO C2 going northward starting around UT 14:00

It looks like that may have been a filament eruption near 3602.

At the sixth second of the video (link below) lasting 19 seconds, the sun seems to shiver, as if a global variation in the magnetic field appeared in a fraction of a second. Unless it's a satellite problem?

It's diffraction due to the flare; you see the same phenomenon with both AIA and SUVI, like e.g. in the recent X6.3 flare:

The grid-like diffraction pattern occurs due to the presence of a metal mesh that stabilizes the filters. As you can read here:

Quote

The entrance and focal plane filters are thin film filters comprised of aluminum or zirconium supported by a stainless steel mesh.

[...]

The stainless steel mesh on the entrance filters is known to cause diffraction at the focal plane, and is taken into consideration for the calculated point-spread function (discussed further in Section 2.2). The mesh for the focal plane filters creates a shadow pattern that can be seen in the unprocessed SUVI products. This patterning is removed by applying the flat field correction during the Level-1b production process.

[...]

The entrance filter and the focal plane filters are stabilized by a metal mesh, which can cause a diffraction pattern in the images that is primarily seen during flares and in high-contrast areas.

That's for SUVI, but I'm pretty sure it's the same for AIA; in fact it is:

Quote

1. Entrance Filter (EF), a thin layer of Aluminum or Zirconium supported by a 70 lines/inch mesh. The main function of the EF is to absorb visible light and off-band EUV radiation. The EUV light is diffracted by the mesh.

[...]

3. Focal Plane Filter (FPF), a thin layer of Aluminum or Zirconium supported by a 70 lines/inch mesh. The main function of the FPF is to absorb visible light and off-band EUV radiation. The EUV light is diffracted by the mesh.

There's even an entire section there dedicated specifically to diffraction from the mesh, which is accounted for just like for SUVI (but which isn't as easy to account for during strong flares); and there's also an illustration of the mesh configuration:

Beta-Gamma-Delta now, but looks like the region is yet again decaying...

I think delta is gone.

I agree. Background flux is already down to mid-B levels (B5-B6), so the region is not even keeping up with background flux, not talking about flares. Unless it once again does a very fast growth and quickly gains magnetic complexity, the region days are counted...

Agreed.  It has a few more days to show us something, however.  The incoming limb wasn’t looking too promising either, dare I look?? Haha. Anyway this isn’t unusual at all during our ascent towards solar maximum.  I was going to review cycle 19 again which had an even worse falloff in flux and activity if I am not mistaken and will share those results here if I have time.  Later. Mike.   Anyway, in cycle 19 march of 1958 we went from about 90 sunspots logged to 340 within one rotation.  A corresponding increase in solar flux recorded about March 21 of that year of 350 was selected as solar maximum subsequently.  So I remain confident we have more in store.   Proper credit to Jan Alvestad Historical Data charts for data I used here.

Isn't this area still a delta?

Looks like it, new growth anyway. And 3599 just spit an M class, so likely correct. 

To me the really interesting thing is as of today 3/9/*24 this one has 18 sunspots yet only size 15MH - so compact. 

*I have completed my time travel and am back in the proper year lol

I think there must’ve been a minor error in MH calculating yesterday.  In any event its back to producing as we can see… delta is back too.

Sudden M7.4 flare 😎

Boom! M7.4...

Very impulsive flare, but of course it starts to activate just as it is approaching the limb.

CME shooting northwards it looks like on the early images.

Yes, I spoke too early - I also see some movement in SUVI, mostly northward.

Brand new poster here, total amateur enthusiast. I just wanted to say it's really cool to check out SUVI 304 on this one. It looks like activity starts around region 3605 and makes its way through 3599 (m7.4 triggers) before ending at 3602.

on a side note, SUVI 304 also shows a significant eruption of some kind just before on the far side, looked like it was pretty fast!

Welcome!  

Yes, I also saw that there was that first major far-side eruption (which looks AMAZING), then an initial smaller flare around AR3605, then our main target - M7.4 flare in AR3599, and then bright material all the wat to AR3602. I would say it is some sort of "flare complex" where one flare triggered another and so on.

I checked SDO images and I see a nice dimming north-northeaster from the flare. Now we need to wait for LASCO coronography...

So not much earth directedness?

yep yep the old waiting game. but i wonder if its gonna be earth directed and if yes how much. not much familiar with northward eruptions. your best guess?  

Lasco imagery has come in but it does not look very huge or anything to me.. @mozy
