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

I was unable to tell which star was the primary, so the PA appeared to be either 203\u00c2\u00b0 or 157\u00c2\u00b0. Separation seemed to be about 10 arc seconds. WDS values from 1783 are 210\u00c2\u00b0 and 9.3 arc seconds. That’s a pretty old measurement, and I’m not sure how close it is to a more modern measurement. But it was close to what I saw. Colors appeared as white for the northeast star, and pale yellow for the southwest star.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
