\nOctober 18, 2006: To help provide a consistent style for my double star sketches, the above sketch is a digital update to the original sketch.<\/i>
\n<\/p>\n

Observation Notes:<\/b><\/p>\n

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\u00c2\u00b0 and a separation of 18″. Listed values from the AL double star list are 85\u00c2\u00b0 and 12.1″. I didn’t do so hot on the PA there.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
