cheebee Posted January 26 Share Posted January 26 couple of good looking filaments there, i wonder if they lift how the coronal hole will change. Link to comment Share on other sites More sharing options...
Drax Spacex Posted January 26 Share Posted January 26 Filament launch shouldn't affect the coronal hole (unless perhaps it produces coronal restructuring with a canyon of fire). How can we know if that is filament or a long, thin coronal hole? Link to comment Share on other sites More sharing options...
Popular Post cgrant26 Posted January 26 Popular Post Share Posted January 26 (edited) AIA 304 Red wavelength gives a bit better view of filaments IMO. In either view it's easier to pick them out in the videos than the stills. I always like when you get a strong snap with an accompanying flare as well as a shockwave that ripples out from where the filament spanned. Really beautiful to see.

cheebee Posted January 29 Share Posted January 29 i think that little one south centre is about to let go, it kind of brewed up all of a sudden, i might be a bit late, it may have already lifted, but it looks very central, the pic doesnt even make it look like a filament cos its gone so fuzzy as its lifting Link to comment Share on other sites More sharing options...

cgrant26 Posted February 6 Share Posted February 6 (edited) And it did! Nice full-halo with impressive symmetry on C3. As is usual with filament eruptions, it doesn't look to be moving all that fast so I'm not getting my hopes up for any really big storms but it sure looks pretty.

Filaments usually dont produce full halos, @tniickck said its a far side eruption. im confused? Link to comment Share on other sites More sharing options...
Maciej Dunst Posted February 6 Share Posted February 6 Yes, filament was not so big, but it was definitely an earth directed eruption. IMO we could have decent auroras from that, but not so intense geomagnetic storm. G1, maybe G2 if BZ will be favorable. Link to comment Share on other sites More sharing options...
MinYoongi Posted February 6 Author Share Posted February 6 @cgrant26 the CME emerged after 12:00 UTC, there is nothing on the visible disk for that time (i checked suvi starting 11:20 UTC) @Maciej Dunst When did the filament erupt? i think i can only see the end of the eruption in suvi then. but i dont think its related to the big CME on lasco after 12:00 UTC.

Could very well be. It does feel kind of early for Lasco to show a halo on that filament. It definitely ejected some material to the North so if we see another puff on Lasco to the North in the next couple hours we'll know that pretty halo was from something far-side.

If eruption was placed near the disk center, full halo is nothing unusual. Those characteristic bulb CMEs we commonly see on LASCO are usually limb eruptions, or near-limb.

I dont know when it erupted but if you look at Suvi : https://www.swpc.noaa.gov/products/goes-solar-ultraviolet-imager-suvi starting at 11:20 UTC right now and go forth to almost real time, i dont really see a corresponding movement Just now, Maciej Dunst said: Why not?

Like i said, the time does not match the CME posted by @cgrant26, there is nothing 40-50 mins before in suvi Link to comment Share on other sites More sharing options...

cgrant26 Posted February 6 Share Posted February 6 First sign of anything on C2 was at 12:12 UT, the SDO 304 frames from 12:08 and 12:18 definitely have that filament lifting off at the same time. At this point I think a simultaneous event on the far side seems pretty likely but the timing is too close for me to rule out this being from the filament. Some pieces (like SUVI) don't seem to fit so if I were a betting man, I'd hold on to my money on this one. lol Link to comment Share on other sites More sharing options...
MinYoongi Posted February 6 Author Share Posted February 6 update: I looked at it, but i have to be honest it looks like its shooting straight northwards and its a not really big filament.

Jesterface23 Posted February 6 Share Posted February 6 As seen in SDO imagery there was a large eruption over the northwest limb. The full halo is not a filament eruption. 2 Link to comment Share on other sites More sharing options...

So probably there were two simultaneous events... Link to comment Share on other sites More sharing options...

But do you mean one event on the farside? i hope you dont think im trying to argue. im really just trying to find out (also i cant add more reactions today, sorry!)

Yes, the large halo is a far-side event and the filament eruption is in that circled area. 2 Link to comment Share on other sites More sharing options...
