Abstract:
The results of astrometric and photometric investigations of the
poorly studied open cluster NGC 1513 are presented. The proper motions
of 333 stars with a root-mean-square error of 1.9mas/yr were obtained
by means of the automated measuring complex "Fantasy". Eight
astrometric plates covering the time interval of 101 years were
measured and a total of 141 astrometric cluster members identified.
BV CCD-photometry was obtained for stars in an area 17'x17'
centered on the cluster. Altogether 33 stars with high reliability
were considered to be cluster members by two criteria. The estimated
age of NGC 1513 is 2.54E+08 years.
