Abstract:
    A CCD photometric study of the dense galactic open cluster M 37 is
    discussed. The majority of the analysed data have been obtained
    through an RC filter in order to collect time-series measurements.
    The observations were carried out on seven nights between December
    1999 and February 2000, and have led to the discovery of 7 new
    variable stars in the field. Three of them have been unambiguously
    identified as W UMa-type eclipsing binaries, while two more are
    monoperiodic pulsating stars, most probably high-amplitude δ
    Scuti-type variables. Two stars seem to be long-period eclipsing
    binaries without firm period determination. The individual light curve
    data are presented here.
