Increasing activity on the Sun

Posted by David Arditti at 01:13 on 2010 Mar 22

I though appropriate to the first post in these new forums might be to point out the increasing level of activity on the Sun in recent weeks, particularly in hydrogen alpha. Anybody who has a hydrogen alpha telescope but has not looked recently should do so. Whereas last year the Sun was quiet most of the the time, now there are obvious active areas and filaments on the surface most of the time, and there have been several major prominences visible in the last week. Here is one I imaged on the 16th:(More images of recent activity on my page 2010 solar images)David
