2916 spot looks to be worth watching already

I am also pretty new when it comes to trying to classify sunspots, but it does seem like a delta spot is beginning to emerge in its trailer region. Very small right now, but seeing negative polarity spots appearing next to the darker positive spots within the penumbra. It's really grown today!

 

Good, I thought that AR was tending to decay more than develop

At one point (a day or so ago), I think there was some slight decay noted, but it has definitely bounced back. 2918 has also exhibited some growth too, but it's not as complex as 2916.

This region may not be as extreme, but it partially reminds me of sunspot region 2371 from 2015 for comparison,

To me it looks like it has a delta but I could be wrong

 

2916 is trying to form a delta, penumbral area is already there but no clear spot.

but everyone misses that 2918 has a delta spot in the northern part of the region…

So it should be Delta right?

2918 beta-gamma-delta with two delta spots. I've taken a closer look on my desktop and marked the two delta's:

In 2916 it's only a pore (barely visible) that if it grows to a sunspot it can be delta, but the region is still only beta-gamma:

And the ones just below it are just so close to the penumbra of the bigger one

And why is it showing up as just beta on the app

Which region are you referring to?

The app take silver the official magnetic classification of the regions during the observation hours of SWPC once per day, because sunspot regions evolve, the magnetic classification can change. It’s not continually updated! That’s why we always analyse solar imagery once they get interesting to make our own magnetic classification.

AR 2916 is huge. Biggest sunspot I have seen so far. 

(By the way Merry Christmas everyone!)

I was referencing 2016 and ah

Also I can see little delta spots where you highlighted so maybe a beta-gamma-delta

Classification is easy if you know what to look for. That’s why I highlighted it on the images. I’ll do that frequently when regions get interesting. 
it’s actually more like beta-delta, not beta-gamma-delta because it’s still easy to draw a line between the two polarities making it not gamma.

Apparently, 2916 is now classified as Beta-Gamma-Delta. Although, there's been barely any flares from it, with the last one being just a C1.4.

But now it increases out chance for an x-class or a proton storm

See, I was right 😁, except the gamma 😜. A beta-gamma-delta doesn’t mean it will constantly have solar flares! I remember several beta-gamma-delta regions that where just quiet even though they had a strong delta. Much will depend if the delta structure gets stronger, if that’s the case it sure will flare or build up energy for a bigger solar flare. We’ll see how it evolves further.

It’s continued to grow, and kept the beta gamma delta!

Getting to be a pretty serious sunspot, one of the better ones of this cycle afik. 
It has the capability of X-class flares, let’s hope it does have one while it’s Earth-facing!

This time I read that right 😂

While it has grown, its overall output of flares and associated energies has waned. This is interesting for a few reasons. Let's keep an eye on it via SDO.

Hold your horses, no X-class is going to happen! If you look at latest imagery there are zero delta spots, thus the region is now only beta-gamma. Yes it has grown but in the penumbral zones you don’t see spots of the opposite polarity so no magic for significant solar flares.

[Solarflaretracker200]

It’s just a B. Which if I’m not mistaken it’s a beta now.

I would still call it beta-gamma, although It’s still easy to draw a line, its polarities are still a bit mixed.

Sad. Let’s hope this goes like the last time you discouraged the sun and it proved you wrong!

I will be mad if it develops and pops off an X right at the limb. It seems to be the SC25 curse 😂

[Solarflaretracker200]

I would  be happy if I can see a X class happen on the live data.

Wouldn’t we all. However, since it’s lost it’s Delta, that seems unlikely. 

[Solarflaretracker200]

AR 2916 is growing again! Yesterday it was shrinking. Still no chance of X class though.

Despite the growth, it didn’t get more magnetically complex so it stays quiet…
