More 904

This afternoon I had another chance to observe active area 904. While I still had to do battle with cloud I did have the time to take a naked-eye look (via eclipse shades — yes, I could see the main spot) and I also had the chance to do a couple of rough sketches (an attempt at a general view of the Sun and also an attempt at some detail of 904).
