Description

There isn't a lot of information concerning this very old open cluster, except some info found in an article of the Astronomical Society of the Pacific stating that :

-"If the group is real (real cluster), it is a very ununsual open cluster. The member stars are very unlikely to be in orbital motion about each othre, thus it is most probable that the group is a residual core of a small open cluster whose fainter and less massive members have had time to dissociate from the loosely bound group. It seems to be an old open cluster near the end of it's life."

Moon was there, I took time to look at something ununsual from my polluted urban sky.
