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

Poor seeing chopped the view up a bit on this double. The primary appeared light blue with a subtly yellow secondary. Both stars are A5V however. PA appeared to be 110\u00c2\u00b0 with a separation about 30 arc seconds. Actual values are 104\u00c2\u00b0 and 22.3 arc seconds.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
