Solar Astronomy: Seeing the Sun with three name tags


I spent a fun couple of hours this afternoon sharing views of the Sun through my telescopes at the Westlake Porter Public Library. It was a sort of sidewalk astronomy event, part of "Science Week" there, and drew 53 participants. Lots of passing clouds got in the way, shoved along by steady winds, and people were surprisingly patient waiting for the Sun to return. When we had clear skies we were rewarded with very good viewing of a beautiful loop-shaped solar prominence through the 35mm Lunt Ha scope; careful viewers with moments of better seeing spied several more! Seeing wasn't quite good enough to reliably find the two small sunspot groups visible today, nor was it good enough to see granulation patters this afternoon. I did see granulation this morning during testing at home. Sadly, a very large sunspot group, visible only days earlier, was just over the Sun's limb this day. Procrastination in these things isn't good but it was well worth the morning's last-minute effort of fabricating a sturdy piggyback mount to mate the Ha with my trusty old Meade 390. It took just two trips to the hardware store for less than $10 worth of parts to create an excellent mount! A newspaper reporter asked me what organizations I represented and it turns out there were three: Cuyahoga Astronomical Association, Stephens Memorial Observatory (Hiram College), and the library! And I wore three name tags.
