Scientific paper

We have obtained good BVRI light curves for the binaries V382 And, V443 Cep, V741 Cas, and V744 Cas. These systems were only recently determined to be binaries based upon observations with the Hipparcos satellite. Our observations were made with the 0.4-m telescope and CCD camera at the Valparaiso University Observatory. These observations have led to improved periods for these binaries, which range from 1.5 to 9.1 days. The systems are all bright, V=8-10 mag, and the eclipses are shallow, with depths of 0.20-0.23 mag in V. The light curves will be analyzed to determine light curve parameters. This work was supported by grants from the Indiana Space Grant Consortium and the NSF (9900846).
