Dear colleagues!
I would like to send you observations of a new variable star (Brh V93),
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 V93 182203.3 +072137 (J2000) 12.7-13.0 (CCD) SR
comments:
Brh V93: GSC 444 2502
The comparison star is GSC 444 2300 (12.3 mag),
which has been checked for constant brightness.
The colour (USNO A2.0 r: 11.8, b: 14.2) and the apparently
slow change of brightness suggest a SR-variable.
Other types of variability cannot be excluded.
