I observed a solar prominence change over 2 hours yesterday afternoon, it was an absolute thing of beauty.
I took my Coronado PST and my 8″ Dob to the New Haven Middle School carnival, and set them up in the middle of all the activities; My wife, Connie, was selling pretzels, and was making sure that everyone knew they could look thru my scopes – no tickets required!
When I’d setup, there was only one tiny prominence on the limb, and I was rather disappointed that I would not be able to show anything interesting thru the PST 🙁
After an hour, another started directly opposite, and I got to watch that one change over the next of 2 hours. It went from a bump, then elongated out, split into 2 shafts twisted around each other – like DNA. The top flattened out – like a thunderhead, then it disconnected, and a football shaped piece got REALLY BRIGHT above the limb, then the whole thing started to dissipate. There were 2 large sunspots, and several smaller ones; several people saw a filament in the PST.
The best thing that happened that day was one of my wife’s students telling me that I had gotten her into Astronomy, and she went out to look at the stars frequently now. It warms the heart!
