2994, i dunno. Something is up. image.jpeg.1628a26490f0b31860c39cb0efd912e9.jpeg

What do you mean by something is up?

 

Thank you for the picture! I hope someone here can confirm the Delta.

2993 looking a bit more interesting compared to yesterday, spots of opposite polarity don't seem as spread out anymore, still nothing impressive, hope it keeps building with more spots.

Thank you. Noaa said one of them is degrading, thats why i asked

Good spot, I wouldn't call it delta just yet, but if it grows & expands then yes it definitely has the potential to be one.

@MinYoongi, sorry for being vague. What I ment is that I believe that AR2994 is about to develop a delta spot, or has already. It's visible in the HMI-images also. Although "old in this game" I'm still uncertain when it comes to sunspots.

Oh, i see it now! Is that a small delta? 

Oh please, youre fine! I look at those Magnetic Layouts like its chinese :D I can tell Alpha and Beta and thats it!

Oh, good. I see that I am not alone in this regard.  (You may have noticed there are no Greek letters in any of my comments...yet.)

Hello all

I checked once LASCO pictures and as far as I can say this M9.6-CME looks
like a small, not earth directed CME pushing the material away about 45°
upwards. This 45° upwards trend I saw already a lot this cycle and also the
limb-X2.2 put the most of the cloud 45° downwards and not earth directed.

Printscreens for the gif-subtractiom animation are taken from 08:42h and 12:42h

Regards, Chris

Which was expected as both events where kind of impulsive short lived events.

@mozy Cheers! Lets see :) Visible in HMI also. 

not delta as it isn’t in the penumbral area of the main polarity. But there is a tiny little speck (get the magnifying glass) visible that is opposite polarity but it has to grow in the northern part of the trailing spot between two spots:

in 2993 there is hope in the northern part where the penumbral area of spots of opposite polarity try to merge with the main polarity which is interesting:

About that 2am event... did anyone take a look at AIA 1600? It's interesting (and following the event the channel shows a lot about how the various spots are interplaying - that channel isn't boring at the moment).

There's just so much to unpack in this about what's really going on, with rings containing perpendicular rings and helical jets... Well... an image tells a thousand words, or maybe a million in this case:

We got action again

Edit: Or not, Just an upper C-flare pop 😎

But the background flux is (still) higher!

So we could call that positive development or is it to tiny/early to tell yet?

But how could that radio emission/shockwave..whatever, reach us, but the xrays didnt?

The radio emission is propelled by the leading edge of a CME shortly after launch. So, it could have come from the CME after launch, in which case it could be possible to receive it from over the limb.
