Included are 17 observations of stars brighter thanseventh magnitude, 13 reappearances, four angular diameter measurements,and seven observations of stars that are either binary or may be double.The observations were made with Stromgren y filter, the u or b filter,or the FI filter described in the first paper of this series (Radick andLien, 1980). Five observations, including four of Aldebaran, were madewith two filters centered on or near H-alpha.
