Observations by Tom Droege with the TASS Mk IV system, together with
the original observations by Bernhard [vsnet-newvar 1395], show that
BrhV103 = GSC 0763-0572 is a W UMa eclipsing binary with a period of
0.4263 days. A 0.1 shift in V had to be applied to bring the two data
sets in line. The amplitude is 0.55 mag for the primary minimum, and
0.45 mag for the secondary (the latter has not been completely covered
yet). TASS has V-Ic=0.60+/-0.04, and Tycho-2 gives BT-VT=0.75.
