Struve 331

October 18, 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:

The seeing was poor in this part of the sky and the color of the stars hard to determine. If anything, the primary was pale yellow, and the secondary blueish. I estimated PA at 70° and a separation of 18". Listed values from the AL double star list are 85° and 12.1". I didn't do so hot on the PA there.
