Abstract

Photoelectric measurements of early-type stars obtained at La Silla in the years 1990 to 1994 with the ESO 50 cm telescope are presented. Most of these data were already used in studies of several binaries.

Now all data were reduced by with an advanced technique and are made available electronically. New light curve and its solution for the binary MY Ser are given.

The result is that this is a contact binary with large fill-out parameter.
