Long Duration Events

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....

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.

I agree! It's helping me recall many things I learned from Dr.Skov's courses.
