Equal pair of very dim stars. Primary a warmer color than the secondary. And here is the interesting thing of this pair, there seems to have been a change as to the primary and the secondary designation over the years, as the WDS has 131 for PA and the project 311. Since the magnitudes are 10.22 and 10.24 this seems like a toss-up anyway. Measured, 3.0 sec at 129.5 deg PA, or 309.5 if you like.
