i will talk about sunspot 2824

sorry for the weird title, sunspot 2824 that right now when I'm writing I'm causing class C solar flares, 3 classes C for now, its structure is very simple but its small points that it has I don't know if they are  forming weak delta points and that is what is causing the call c activity right now, If I'm wrong, well I just wanted to see if what I think is correct or not

No delta’s ;) simple spot configuration but some impulsive C-flare activity with a possible CME as there was a type II and IV radio burst and weak dimming

thank you very much for answering,

What does it mean, will the enhancement end or continue 

I'm not sure. Hopefully it will spread across the remainder of the sunspot and mature into a super long duration flare. I don't think that is very likely, but you never know.

What is an enhancement 

I not sure of the exact terminology. I have seen SWPC use it. I have taken it to mean an enhancement in x-ray flux from the coronal loops. They can last for many hours, but don't tend to release a CME like a long-duration flare. Not sure what the exact distinction is though.

No. It is an enhancement in sunspot 2824. You can see it in the 94A imagery.

However, it is said that it belongs to a high duration flare from the forecast discussion in swpc. Slso, it has appeared that the glare or enhancement ended and background flux ended up abou b2

Perhaps it is a flare. The x-ray flux has not yet returned to background levels. In 12 hours it should be down to b1. The sunspot does look to have gained a little magnetic complexity, with more negative polarity spots emerging around the main spot.

And we have an Impulsive M1.19 solar flare from this region. It’s getting better, and indeed nice spot development 👍

There is coronal dimming again with this one. Looks like it is mostly directed to the south. This region seems to have a habit of producing prolific, weak, and highly asymmetric CMEs. I think we would need to see an eruption covering the whole sunspot to get a decent Earth-directed CME. So far they are all blasting sideways constrained by the unbroken coronal loops.

Hi! 

Today was a busy day for our Dwarf star and active region 12824 !

 

Many impulsive flares, dimmings and radio sweeps.

NOAA mentioned some CME's in their forecast and i checked Nasa Enlil (click here to look at it) because Noaa hasnt updated their enlil yet.

And it looks like only 1 glancing blow, but theyre speaking of multiple earth directed CME's with earth facing componentes, does someone want to look at them with me? I just wanna look at each in depth. 

Are there some not noteworthy, not earth bound at all? 

What KP do you expect upon arrival? 

 

Thanks in advance for everyone willing to discuss and look at it together!  :)

A beautiful animation of the development on helioviewer:

https://helioviewer.org/?movieId=MgXN5

It also gained a bit of area.

That is a nice detailed animation.  It appears to be centered on the sunspot, and we do see the surrounding area moving away from that centered sunspot.

However, it's somewhat difficult to tell whether the true size of the sunspot group is increasing in area.  As a sunspot group moves across the solar disk, it will appear to increase in size (width) as it rotates toward the center of the solar disk, even if the actual size (width) has not changed.   The factor by which the group is foreshortened in width is, I think, proportional to cosine of the longitude position of the sunspot group (-/+90 degrees with 0 in the center).

Note that in the animation, it's not  not expanding vertically, only horizontally.  This is a clue that the actual area may not be increasing, and instead what we're seeing is just a reduction in the foreshortening as the group moves closer to the center of the solar disk.
