Dear colleagues!
I would like to send you observations of a new variable star (BeV23),
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 BeV23 200936.1 N103909 (2000) 12.6 13.0 (CCD) SR
comments:
BeV23: GSC 1076 1805
Comparison star was for all measurements GSC 1076 1346 (12.3 mag),
which was checked to be constant.
The change in brightness and the red colour
(USNO A2.0: r:12.8 mag, b: 15.3 mag) suggest a SR-variable.
