Manu Posted September 6, 2022 Share Posted September 6, 2022 Hello, I would like to know whether a filament eruption can provoke the same geomagmetic effets as a big CME induced by a X10 or higher flare ? Do filaments need a nearby flare to erupt or simply from intrinsic instability? Thanks Link to comment Share on other sites More sharing options...

Very rarely a filament eruption can produce a strong CME, but it’s rarer than for a very strong flare to do so. And we don’t know of any filament eruptions that can produce a CME as strong as, say, a Carrington CME. So, basically, sometimes but rarely, and not the suuuper strong end. 27 minutes ago, Manu said: Do filaments need a nearby flare to erupt or simply from intrinsic instability? They usually explode from intrinsic instability. Sometimes they are trapped by the sun’s gravity and fall back into it without producing a CME, but sometimes they do escape and form a CME. A nearby flare helps launch them, but they often (maybe usually) explode or collapse by themselves. 1 Link to comment Share on other sites More sharing options...

No, filaments just don't have the escape speed comparable to events caused by very powerful solar flares. I do not think I have ever seen Kp8 or higher caused by a filament. 1 Link to comment Share on other sites More sharing options...

I feel like I remember someone telling me about one G4(KP8) caused by a filament, but I might have dreamed it... or maybe it was the only one in history. I do think it was a really long time ago, pre-2000 maybe. But in the vast majority, I feel like G1 is normal for filaments, G2 is a good one, and G3 is the realistic maximum. 1 Link to comment Share on other sites More sharing options...

The big one in the mid on the south is going off now, what´s about this? BR Link to comment Share on other sites More sharing options...

Manu Posted September 7, 2022 Share Posted September 7, 2022 (edited) Thanks guys for the very informative answers ! @Jen Seits what do you mean by 'going off'? Edit : I mean how do we see that? Apparently this one on August 31st, 2012 triggered a G2 storm (from location S06E20). It was not exactly centered but still launched a halo CME Edited September 7, 2022 by Manu 1 Link to comment Share on other sites More sharing options...

Landon Moeller Posted October 2, 2022 Share Posted October 2, 2022 The filament in the SE portion of the disk has been dancing a lot more over the last few hours. Looks like it may erupt soon and result in a CME. Hopefully not too south for earth but it probably will be Link to comment Share on other sites More sharing options...

Landon Moeller Posted October 4, 2022 Share Posted October 4, 2022 A filament in the Sun’s southern hemisphere just rapidly lifted off the sun in the last hour, and despite it being so far south, it may very well have an Earth-directed component!

CMEs don't always launch in precisely a radial direction normal to the Sun's surface. 2 Link to comment Share on other sites More sharing options...

Back to the filament, this one looks a lot more likely to be earth directed than the filament eruption late on Oct 2. 2 Link to comment Share on other sites More sharing options...

Nice, do you have imagery for me? on mobile and cant look at sdo movies sadly cuz their page isnt optimated for mobiles. Was it a narrow eruption / Glancing blow or full hit?

Was it a narrow eruption / Glancing blow or full hit? It was a horizontal filament which seemed to lift off with a northward component, but STEREO imagery is not very promising. Doesn’t even look like a glancing blow 2 Link to comment Share on other sites More sharing options...
