[Starman]

Hi all,

Working through all of the AVIs I've taken recently - very slowly. Here's a mosaic of the three active regions in H-alpha taken on the 29th March.

Full sized one here:

Blimey Pete, that's a superb shot. :shock:

That's an awesome shot! What's the stuff below the spots (the long dark patch)?

The dark line is a prominence - plasma thrown up off the Sun's 'surface' and held in place by the Sun's magnetic field. You're probably more familiar with them when they appear on the limb like giant arching flames. When they occur on the Sun's disk as here, they're called filaments.

Thanks Starman!

I could feel the heat just looking at it.

Another superb image Pete.

Beautiful shot.

I note today (using the old eyeball) that there are more small 'spots' in the flare area and less eyebrow (as we call bits like the long dark section). The sun changes so quickly hour to hour. There is even a nice flare on the edge.

Fabulous images, Pete - I love the 'dark line' prominence.

Thanks for the comments.

Steve - it was a nice feature. Unfortunately, today (March 30th), it's gone! :shock:
