Dear colleagues!
I would like to send you observations of a new variable star (Brh V91),
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 V91 192050.1 +072314.7 (J2000) 12.8-13.2 (CCD) SR
comments:
Brh V91: GSC 476 575
The comparison star is GSC 476 753 (12.4 mag),
which has been checked for constant brightness.
The red colour (USNO A2.0 r: 12.2, b: 15.6) and the apparently
slow change of brightness suggest a SR-variable.
Other types of long period variability cannot be excluded.
