Abstract his cluster contains about thirty-five visual members with spectral types from B4 V to F0 V. Star ts in the cluster region and in a nearby control region indicate that there are no fainter members [hat the late-type giant stars in the cluster region are probably not members. Radial velocities by uthors and by Trumpler show an unusually high fraction of spectroscopic binaries. The rotational ities by Deutsch for cluster members are low for their spectral types. These three properties (short . sequence, high binary frequency, and low rotational velocities) are the reverse of the characteristics e Pleiades.
