Talk:CMEless Flares

Hi Hugh,

Enjoyed your latest nugget, but have to remark -- your claim that the TRACE movie of the event in the Nugget shows the usual flare morphology: two ribbons and a loop arcade is (in the words of the memorable Chang-Hyuk An) "hard to believe". In particular, the late-phase loops look very non-potential -- much different from the standard arcade that one sees in an eruptive event!

Best wishes,

Dick

Well, that is an interesting comment and so I'll put it into our "notes" section. I think you're right, standard arcades can look pretty potential, but appearances can be deceptive. I know of a couple of examples when a proper arcade formed - the ground state of the field, one might argue - but then the arcade erupted!

Anyway, I think these flares have been ignored for too long. If interested you might check out the Wang & Zhang 2007 article we cite; it is about the magnetic environment.

Cheers

Hugh
