August 7, 2005 Observation
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 170Â° and separation at 8". Listed values from the AL double star list are 0Â° 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 350Â°. Now, I've grown accustomed to my PA value being off by as much as 10Â°, but I'm positive these stars didn't line up perfectly north - south. I checked the WDS catalog and a value of 356Â° was given, so I'm somewhat vindicated there. Not that I need to be vindicated. Uh. Where was I?
