Youcef Posted February 28, 2021 Share Posted February 28, 2021 Yesterday 2 cme's fired off and today another one possibly caused by a sundiving comet! Solar wind stream flowing from a Southern coronal hole will reach us on the 1st or 2nd of march 2021. Density and speed are both low so I expect it to be a weak impact.

Vancanneyt Sander Posted February 28, 2021 Share Posted February 28, 2021 Both CME’s where associated with the two impulsive C-class solar flares from 2804. Haven’t seen the sun diver yet 😊. CH is indeed on its way as been reported by us as well. Link to comment Share on other sites More sharing options...

Was it also caused by a sunspot... 16 minutes ago, Vancanneyt Sander said: Both CME’s where associated with the two impulsive C-class solar flares from 2804. Haven’t seen the sun diver yet 😊.

So it seems but you know I didn't mean the sun diving comet created those cme's by itself what I meant is it increased the sun's activity. Contributing those cme's indirectly sometimes however they canmake the sun produce cme's seen it many times happen with a blank sun! Anyway thx for the info helpful in some way, forgot about those sunspots... 😄 Link to comment Share on other sites More sharing options...
Youcef Posted March 1, 2021 Author Share Posted March 1, 2021 Question: is there a way other than the enlil spiral to know if a cme is earth directed or not. Yesterday's cme doesn't show up on enlil... CME Link to comment Share on other sites More sharing options...
Jesterface23 Posted March 1, 2021 Share Posted March 1, 2021 We use the satellite SOHO's coronagraph imagery to determine if a CME is Earth directed. The CME yesterday was small and near the western limb. If you look at the coronagraph imagery it shoots out to the side and isn't Earth directed. The CME a few days ago was Earth directed with a full halo in coronagraph imagery, but was very hard to see. I wouldn't expect an impact from that one with it being fairly slow and the current coronal hole ran it over. Link to comment Share on other sites More sharing options...
Sheaxma Posted March 2, 2021 Share Posted March 2, 2021 Youcef, I liked your video very much! I, too, notice and wonder about unreported solar activity data and blanks in the Schumann Resonance charts. You have a new subscriber! Link to comment Share on other sites More sharing options...
