Eighteen symbiotic stars have been observed with a CCD camera on the Wellesley College 24-inch telescope since 1994 spring. Representative light curves will be shown. Possible periodicity has been detected for UV Aurigae, BF Cygni, AG Draconis, and V443 Herculis. A possible eclipse was observed in the YY Herculis system in 1997 late August.
