Dear colleagues!
I would like to send you observations of a new variable star (Brh V89),
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 V89 171103.3 +071148.1 (J2000) 12.6-12.8 (CCD) L
comments:
Brh V89: GSC 411 150
The comparison star is GSC 411 235 (12.6 mag),
which has been checked for constant brightness.
The red colour (USNO A2.0 r: 12.4, b: 14.7) and the apparently
slow, maybe irregular change of brightness suggest a L-variable.
Other types of long period variability cannot be excluded.
