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

This was a stunning, pair of close orange-yellow stars. Their color reminded me of our own sun’s hue during a clear, warm sunset. PA appeared to be about 130 degrees, which compares with the 1990 value of 123 degrees from the WDS Catalog. The stars were separated by about three first-diffraction-ring widths, center to center, which works out to around 3.7 arcseconds. The 1990 WDS value is 4.6 arcseconds.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
