Dear colleagues!
I would like to send you observations of a new variable star (Brh V87),
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 V87 194836.8 +072117 (J2000) 12.7-13.2 (CCD) SR
comments:
Brh V87 does not have a number in GSC.
The comparison star is GSC 492 1481 (12.5 mag),
which has been checked for constant brightness.
The red colour (USNO A2.0 r: 11.9, b: 15.2) and the apparently
slow change of brightness suggest a SR-variable.
