I would like to send you observations of a new variable star (Brh V146), which I have discovered in a systematic CCD-based search for new variables. In each observing run typically 600 images are taken of several survey fields. The frames are processed automatically.

CCD-camera: Starlight Xpress SX (unfiltered)
Telescope: Celestron-8 (20 cm Schmidt-Cassegrain)

New variable star:
new Brh V146 06 55 57.5 +15 35 32.9 (J2000) 12.4-12.8 (ROTSE)

Brh V146: GSC 1331 726

The comparison star is GSC 1344 1959 (11.4 mag), which has been checked for constant brightness.
The following observations and the ROTSEI data suggest a WUMa variable with a period of about 0.3506 days. The ROTSE data are available at
