Dear colleagues!
I would like to send you observations of a new variable star (Brh V84),
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 V84 190053.0 +071203 (J2000) 12.3-12.7 (CCD) SR
comments:
Brh V84: GSC 474 323
The comparison star is GSC 474 195 (11.9 mag),
which has been checked for constant brightness.
The red colour (USNO A2.0 r: 11.4, b: 14.0) and the apparently
slow change of brightness suggest a SR-variable.
Other types of long-period variability cannot be excluded.
