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

This was a stunning pair. They were so close in magnitude, I couldn’t tell the primary. At low power, both looked light blue. But at high power, I’d say the northern star was light blue while the southern star was white. If anything, the northern star may be a touch brighter. I estimated PA at 170\u00c2\u00b0 and separation at 8″. Listed values from the AL double star list are 0\u00c2\u00b0 and 7.8″. Not bad at all on the separation estimate! Apparently, they have the southern star pegged as the brighter one, so my PA should actually be 350\u00c2\u00b0. Now, I’ve grown accustomed to my PA value being off by as much as 10\u00c2\u00b0, but I’m positive these stars didn’t line up perfectly north – south. I checked the WDS catalog and a value of 356\u00c2\u00b0 was given, so I’m somewhat vindicated there. Not that I need to be vindicated. Uh. Where was I?<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
