Abstract (from CDS):

A photometric monitoring program in the field of the Galactic cluster NGC 6939 was conducted using the 0.91 m WIYN and the US Naval Observatory Flagstaff Station 1.3 m and 1 m telescopes, with the primary goal being to search for cataclysmic variables (CVs) in the cluster. Although no CVs were found during the 5 months of monitoring, a number of short-period variables were discovered in the field of the cluster. A large portion of them are of the W Ursae Majoris type, whereas WOCS V7 is an RR Lyrae star. Although the survey was somewhat compromised by the bright stars around the center of the cluster, it is intriguing that NGC 6939 appears to be deficient in faint variables.
