It came back at 2:00Z this morning, so I'd expect it to come back around the same time again. 1 Link to comment Share on other sites More sharing options...

It showed signs of instability for a little bit now. It looks like this little area of negative polarity was centered around it Edited February 10 by Parabolic Used wrong jargon Link to comment Share on other sites More sharing options...
hamateur 1953 Posted February 10 Share Posted February 10 (edited) Nice! Almost an X. More to come later I suspect! About time. Picked up spots and surface area today regrowth for a change. Bravo. Keep it up 3576 Edited February 11 by hamateur 1953 Kudos to performance Link to comment Share on other sites More sharing options...

I am pretty confident we'll get a fair portion of a solar storm. I'm more worried that the solar storms from the filaments will impede this solar storm 😅 1 Link to comment Share on other sites More sharing options...

Drax Spacex Posted February 11 Share Posted February 11 Did this flare create a coronal hole? Or maybe just "coronal restructuring." https://ibb.co/VqRs0vz 1 Link to comment Share on other sites More sharing options...
Philalethes Posted February 11 Share Posted February 11 (edited) Here I've drawn in some things to consider: The red square is some coronal loops that appear to remain relatively static throughout the imagery and obstruct the observed dimming, but it looks like the dimming extends in that direction too, leading to a temporary little coronal hole (the dimming) corresponding roughly to the yellow circle. I've roughly drawn in the center of it with green and a green line connecting it to the origin, giving perhaps some idea of the angle. Actual numerical estimates based on this rough sketch are likely to be wrong, but if we consider only the northwards component and a basic assumption of how far up that hole is we can estimate the angle in the northwards direction; we could say the dimming we're seeing is a hole at around ~0.5 Solar radii above the photosphere (this will probably be the biggest source of error, I don't really even know if it's close to correct, I couldn't find any good data on it right now), and observe that the northwards movement as we see it in two dimensions is also ~0.5 Solar radii, which would imply a ~45° angle northwards. This would of course be wildly different depending on high up you assume that final dimming to occur, if you were to assume it's just ~0.25 Solar radii instead then the angle would be just ~26° (i.e. 64° northwards), and vice versa if you assume ~1 Solar radius of height instead. Hence why I wouldn't use this for an estimate without a better idea of that height, but it should at least give some visual representation of what's going on.

Or maybe just "coronal restructuring." https://ibb.co/VqRs0vz In a thread long ago I did find some papers, including some comments by Scott, which said that there wasn't really any practical difference between the temporary dimming following ejections and the more permanent coronal holes; thus why such dimming is also often referred to as a transient coronal hole. Dug up the post, it's this one. 3 Link to comment Share on other sites More sharing options...

Might be time to dig into the archives... I believe Dr.Tamitha Skov explains this in one of her mini courses. Also, if you go back and watch AR3575 you can see it 'eat' the CH it formed next to. It started sometime early 02/03. I thought that was very interesting and never seen it before 🙂 Link to comment Share on other sites More sharing options...
