\nOctober 9, 2006: To help provide a consistent style for my double star sketches, the above sketch is a digital update to the original sketch.<\/i><\/p>\n

<\/p>\n

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

This doubly was very close to a brilliant star. The primary is orange. The secondary is white. PA appears to be 240\u00c2\u00b0 with a separation of 1′. The bright star to the east is yellow orange and about 8′ away. After checking the listed data, I have to say ‘oops’. It looks like the brilliant star to the east is actually the primary. With that being the case, PA in my sketch looks to be about 265\u00c2\u00b0 which is a lot closer to the listed value of 291\u00c2\u00b0. Separation of 480″ in my estimate is a lot closer to the listed value of 378″. Still a pretty ugly estimate though. :-\/<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
