Paper Abstract

Based on the data from the "Pi of the Sky" project a catalog of variable stars with a period from 0.1 to 10 days was prepared. We analyzed data collected during the period of two years (2004 and 2005) and we identified 725 variables stars. Most of the stars in our catalog are classified as eclipsing binaries - 464 (about 64%) while the number of pulsating stars is 125 (about 17%). Our classification was based on the shape of the light curve, as in the GCVS catalog. However, some stars from the GCVS catalog were classified differently in our catalog. We found periods for 15 stars included in GCVS catalog as stars with yet unknown period and absent in the ASAS catalog.
