Jef,

Great set of proms--looks like your holiday was a good time. I'm sure your astrosketching presentation was very well received.

Thank you for sharing these wonderful solar sketches. I've not had a chance to look through a Hydrogen Alpha filter. So much detail shown in the prominences. Question: Were some of these prominences changing rapidly ( or at least noticeably ) while you sketched?

Thanks all for the nice comments!

No. You see mostly "some" changes after 15 minutes. But some features can stay almost unchanged during 24 hours. I saw only once a prominence in outburst, where you can almost see it change in realtime. I regret I didn't made a sketch...

Thank you for answering my question. I must get a look through a hydrogen alpha filter.

The sketches are really beautiful, Jef! You got to see some very nice proms and most importantly, you captured them in such a skilful way so that we get to enjoy them as well. Very, very nice!

Peter
