3 Centauri

Observation Notes:

This bluish pair gave the appearance of sky blue for the primary and blue-gray for the secondary. My estimate for PA was 115°. Seeing was very poor in the area, and made the diffraction rings impossible to see clearly. My best guess was 5-10 arc seconds. Actual values are 106° and 7.9 arc seconds from a 1986 WDS measurement.
