Phelps and Janes give the outer cluster radius as 3.4arcminutes and list the minimum number of cluster members as 79. They include a plotted image of the cluster. [Phelps, R. L. & Janes, K. A. (1994) "Young Open Clusters as Probes of the Star Formation Process. 1. An atlas of open cluster photometry" Astrophys. J. Suppl. Series, 90:31-82.]
The RNGC (Sulentic and Tifft 1973) notes that this is a 9.5 mag open cluster.

[0h 33m 6s, 63° 18m 0s] The cluster was not found. A nice but faint double, HJ 1033, was found in its place. WikiSky: HJ 1033 is at the cluster's center. It's a very loose cluster, needing darker skies to show its existance.
