The above sketch shows the sunspot group observed from 15:54 until 16:04 U.T. on 7 July 2009. A 60mm f/11 achromat refractor (Buttercup) was used at 70x for the observation and sketch. Use of a star diagonal resulted in a mirror-reversed view. North is up and preceeding is to the left. It's good to finally see some sunspot activity on our nearest star!
