faster328 Posted August 13 Share Posted August 13 (edited) I am not exactly sure what a long duration event is. The X10.1 from 10720 (β-γ-δ) on 2005/01/20 is a long-duration event unlike the X45 from 10486 (β-γ-δ) on 2003/11/04 which is a short-duration gradual event. The long-duration X28.5 from 5629 (β-γ-δ) on 1989/08/16 lasted even longer, being the longest duration event ever recorded since 1976. I know long duration events are events that last about 30-60 minutes or more. What exactly is a long duration event?

You may find this presentation instructive - particularly from slide 14 onwards.... https://lasp.colorado.edu/media/education/reu/2011/docs/talks/Woods_Flare_Lecture_Jun11.pdf 2 1 1 Link to comment Share on other sites More sharing options...
hamateur 1953 Posted August 13 Share Posted August 13 That is a really excellent link Mike!! There is a ton of relevant information within it. Including TSI which came up recently when a new member asked about Solar Max in another thread. Also includes the various layers responsible for whatever wavelength emissions. Was well worth checking out for me. I always assumed everything happened on the near surface. 2 Link to comment Share on other sites More sharing options...

It's helping me recall many things I learned from Dr.Skov's courses. 1 1 Link to comment Share on other sites More sharing options...
