[vsnet-newvar 1012] New Bernhard variable (Brh V90)



Dear colleagues!

I would like to send you observations of a new variable star (Brh V90),
which I have discovered in a systematic CCD-based search for new
variables.
In each observing run typically 400 images are taken of several survey
fields.
The frames are processed automatically.

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

New variable star:
new Brh V90 195359.4 +071444.9  (J2000) 12.0-12.4 (CCD) SR

comments:
Brh V90: GSC 493 629
The comparison star is GSC 493 799  (12.1 mag),
which has been checked for constant brightness.
The red colour (USNO A2.0 r: 11.4, b: 13.9) and the apparently 
slow change of brightness suggest a SR-variable. 
Other types of long period variability cannot be excluded.
