First CCD photometric observation of the W-UMa eclipsing binary system 1SWASP J064501.21+342154.9

Authors

Abstract

New BVRI light curves of the eclipsing binary system 1SWASP J064501.21+342154.9 (J0645) have been constructed based on CCD observations that were obtained by using the 1.88-m telescope of Kottamia Astronomical Observatory (KAO), Egypt on January and February, 2013. New times of minima and new ephemeris have been determined from these light curves. Using the Binary Maker 3.0 (BM3) package, a preliminary determination of the geometric and photometric element parameters of the system J0645 is derived.
