i'll miss the old threads😭 though new ones are better for the website

Sorry, but these huge threads have to be renewed sooner or later anyway. I have added a link to the old thread in the opening post to hopefully relieve the pain a little bit.

Good thought, thank you!

The blast on the South Pole of the sun at 17/02 13:28 UTC may have been caused by an unstable polar crown filament according to spaceweather.com

We have been seeing more filaments and prominences recently, including near the poles.  This corresponds with the more chaotic magnetic field as we approach solar maximum.  Ahead of the solar pole reversal, as the solar dipole strength weakens, we may see more prominences and eruptions near the poles.

Both CMEs from the 17th seem to likely be linked to a sunspot region given the large shocks of both.

Ongoing eruption (165 Å)? (edit image -> GIF)

That'll be interesting to see in the coronagrams, wouldn't surprise me if we get a little hit from that as it looks now.

My Twitterfolks say so too. what do you say? looking at suvi, most of it went westward if im correct. (i.e the bulk)

Still hard to say, but the general direction did seem that way from SUVI, and also from the latest LASCO imagery:

In one of the previous frames there seemed to be some ejecta that were quite wide, but more imagery is definitely needed.

SWPC already modeled that ICME. As expected, very weak glancing blow at best from this one. 

It's hard to tell exactly what is coming with the HSSs on the east side of the coronagraph imagery, but maybe we can get some sort of CME/SIR arrival. That might be the best chance for any activity

Does anyone know what caused the CME in the northwest currently seen on LASCO C2?? I had noticed a floating filament there hours ago but I don’t see it leaving the surface 

dayum whatever just happened was so powerful a f***ing minecraft block flew out of the sun

Qualcuno sa cosa ha causato la CME nel nord-ovest attualmente vista su LASCO C2?? Avevo notato un filamento fluttuante lì ore fa ma non lo vedo lasciare la superficie 

Today 13,00 UTC a filament eruption in NW

Filament snap east of AR3592 - Type II radio emission 

Looks like a small CME with a decent amount of speed. It looks like there is some Earth-directed component, but not from the best part.

Noting the CME pointing northeast in coronagraph imagery is a different CME over the limb. Actually, on our side around 60 degrees east.

this unstable filament can fire at any moment

Any news on this filament?

There seems to be a Filament or something in the East/South quadrant of the sun. 

Hmm. It's not a bad CME, it just isn't aimed in a good direction for us.

Maybe around 3 days travel time on the later end from early calculations.
