Description:
A triple system with 2 brighter, blue stars fairly close together, with a much dimmer 3rd member much farther away. As I look at this the primary sometimes seems to vacilate between yellow and blue, an illustion which I attribute to the seeing. If one considers the brighter 2 as one vertex and the 3rd member as another, there is a 4th star, about 3 times the separation of the wider members, forming a triangular asterism.
