October 12, 2006: To help provide a consistent style for my double star sketches, the above sketch is a digital update to the original sketch.
Observation Notes:
While finding in the 32 mm EP, the double didn’t show up. Meissa sits at the north end of a trio of pointer stars. It’s a nice tight double. Both stars appear blue, although the brighter component is more obviously blue.
