Sam Warfel Posted February 18, 2022 Share Posted February 18, 2022 We just got a type II radio emission, but there’s no flare that could have made a CME (except some b-class one), so what caused the emission? Can filament eruptions cause radio emissions? Link to comment Share on other sites More sharing options...

MinYoongi Posted February 18, 2022 Share Posted February 18, 2022 (edited) After looking at AIA its from a little (B-Class Flare) Eruption from AR2950. Â Â Update: It happened around 16:30 UTC. Edited February 18, 2022 by MinYoongi Link to comment Share on other sites More sharing options...
Jesterface23 Posted February 18, 2022 Share Posted February 18, 2022 Possibly from an eruption slightly over the west-northwestern limb. Link to comment Share on other sites More sharing options...

Can filament eruptions cause radio emissions? Forgive my ignorance (and I freely admit there is a lot of it) , but the CME log shows this from the 17th with a halo. Is that in any way linked? I wondered how long it takes for type II emissions to be observed after a CME.... respectfully anticipating a sigh and roll of the eyes in my direction.  Edited February 18, 2022 by Cat Perkinton Link to comment Share on other sites More sharing options...

If you look at SDO imagery right is west and left is east. But the top is north and bottom is south. Link to comment Share on other sites More sharing options...

It’s right as the CME launches. 1 Link to comment Share on other sites More sharing options...
Isatsuki San Posted February 19, 2022 Share Posted February 19, 2022 I don't know if I'm seeing correctly, but the great sunspot that the cme launched on the 15th, isn't it two sunspots together? Link to comment Share on other sites More sharing options...

Well, you can't actually use EUVI to see the true sunspots, since they're on the photosphere. It's only good for seeing the features of the corona.

Solarflaretracker200 Posted February 19, 2022 Share Posted February 19, 2022 This region did a filament eruption and a CME? (I am asking because I am starting to track regions earth facing and far side and I want to make sure it's correct) Link to comment Share on other sites More sharing options...
LunarLights58 Posted February 19, 2022 Share Posted February 19, 2022 (edited) From SDO, there it is! It's starting to appear as a bright area on the northeast limb. Edited February 19, 2022 by LunarLights58 Link to comment Share on other sites More sharing options...
hamateur 1953 Posted March 8, 2022 Share Posted March 8, 2022 While we are all waiting with baited breath for you know who to get it’s act together.  I had a thought-experiment pop into my disorganized skull,  what if we were able to actually view you know who as he spit an xray burst at our ionosphere ???  no way could we be hurt, wavelengths are absorbed by our atmosphere but I’d be willing to bet it would look really cool when it wrecked our high frequency ham communications!  just a fantasy no way to observe it probably.   Link to comment Share on other sites More sharing options...
