Abstract

Standardized UBV photometry of seven early M emission-line dwarfs, seven Mira stars, and also SS Cygni is presented. The dMe stars have not been previously observed in the UBV system to the accuracy presented here. The short time scale ( < 1 min.) variations observed in the light output of SS Cygni are similar to those found by Walker and Chincarini (1968).
