Active Region 3614

I found an interesting comparison from AR3614's previous rotation.

These two images are from 02/18/2024 and 03/17/2024 respectively.

hopefully it's hiding something behind the limb like last time

North 16 latitude roughly corresponds to old ‘90    So it probably is indeed. Further corroboration is our baseline solar flux, which at 17:00 utc was approximately 153. Up significantly over the past two days. Probably the southern hemisphere incoming region which apparently just developed is helping push flux back higher too.  The next two weeks are going to be interesting to me anyway.  Hopefully. ‘90 has had sufficient time to reconsider how shamefully it acted last transit and deals us a decent earth-directed geomagnetic storm this time. 😆

Can you explain what you mean by "old '90"? Thanks

I'm just learning; I'll provide a screenshot for reference, but in the magnetogram isn't there clearly a positive and negative pole located within the sunspot? Thanks.

I guess we have to see what it has in check for us this time, would be nice if it rotates fully into view and shows us some good stuff this time. 

it has grown a bit and even has a few small deltas, but it seems to me that the end is near

Imaged this region earlier, doesn't seem like there's much more coming unfortunately. Looks like 3590 hasn't learned it's lesson yet! guess we weren't harsh enough last time haha.

I say this respectfully, but I really doubt it's end will arrive before it reaches the west limb. I also personally think this region has survived two rotations. Correct me if I'm wrong but after doing some very rough research I believe it was possibly first numbered AR3559.

Things can change quickly though and I honestly wouldn't be surprised if it decayed to plage in 24hrs haha.

This would only be its second trip across our side of the solar disk. It developed at some point after February 3rd on the far-side. Old region 3559 is now 3611.

Here's where this region left off before going over the western limb and the region now,

M1 per solar soft. After 3612 on the downslope

Yeah interesting...
It will be nerve wracking!

It’s always a waiting game.  It’s been probably a year since we had the KP eight that wasn’t predicted to go that high either in the states. We are overdue imho. We have a good two or three years by my reckoning of decent active regions, despite what you may read elsewhere.   SWPC and NASA  expect a second peak as do most others familiar with sunspot cycles, good days are still ahead for those 730 days or longer.  We are only 4.5 years roughly into the average 11 year cycle now regardless.  I love this stuff. Haha.  Mike.

Newly assigned regions that appear on the limb often start as alpha until the whole region gets better into view and the magnetic configuration can be seen better. SWPC already upgraded the magnetic configuration to beta.

When I read about the classification system I noticed and copied; 

Delta spots rarely last longer than one rotation of the Sun. They decay quicker then other sun spots. However, new delta spots can form within the same area.

Delta sunspot groups usually do not separate, but rather die together.

 

so I am curious. If 3614 is ol’ 90, but now is a simpler beta class….. does that suggest that 90 died and what we now observe is “new” or is 3614 the result of a complex sunspot growing simple? 
 

I also am just learning.

Thanks for the clarification; very cool! But now I'd say we can clearly see 3614 off the limb. Because the magnetogram seems to show clearly that the positive and negative poles cut through the penumbra, would we expect 3614 to become a beta-gamma or such? Sorry for the crude screenshot/mashing.

3590.  Apologies. This was an active region that distinguished itself by discharging a number of moderate M class flares* on our side of the sun during its transit.    Mike. * with minimal earth-directed coronal mass ejections.

Hopefully all the quiet from this spot allows it to build up for a major x-class flare when to turns to face us!

Is this about to launch something? It looks weird above the sunspot!

im not sure. maybe a filament.

and something is happening there right now! looks like a decently big filament release, although it doesn't seem like its going towards us

Definitely looks like a big filament release, although it seems like a lot of the material rained back down on the surface. It's already visible in the very last image of C2 too.

anything earth directed? I read alot got reabsorbed and too far north maybe.

Hard to say yet, but I agree with both of those by the looks of it.

It looks like it also destabilized the filament running through AR3615. Wonder if it will further destabilize the big filament that is NNE.
