AR1057 Sketch March 27th

I posted this sketch of AR1057 in the Solar Observing forum. A nice sunspot group and a big one, too. The sketch was done at the scope on Strathmore sketch paper with HB, 2B, and 6B pencils. I flipped the sketch horizontally after scanning to conform to standard convention.

Very nice detailed sketch. It has been so long since I have looked at the sun I'll need to hunt down my solar filter.

Jim Ferreira posted this WL image in the solar forum. It's interesting to compare to my sketch.
