Hi all,

The monster Prom lives on today on the SE limb. Two other proms across the disk would be considered large themselves but are dwarfed by that big dog. A good size filament is seen in the disk centre along with some quite active spot groups unusually visible in H-a.

First the H-a view:(edited to get the times right)

Fine sketches. You sketched the sun only 3 hours after Uwe. Interesting to see how fast the surface changes.

Great set of sketches, Mel. That SE prom is a big one--I never got a chance to see it so thanks for the view. :)
