[vsnet-newvar 935] New Bernhard variable (Brh V73)

[Klaus Bernhard <kl.bernhard@aon.at>]

Dear colleagues!

I would like to send you observations of a new variable star (Brh V73),
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 V73 173530.4 +040538  (J2000) 11.0 11.4 (CCD) SR

comments:
Brh V73: GSC 422 1393
The comparison star is GSC 422 663  (11.7 mag),
which has been checked for constant brightness.
The red colour (USNO A 2.0: r:11.5, b:14.0) and the apparently slow 
variation in brightness suggest a SR-variable.
