Dear colleagues!
I would like to send you observations of a new variable star (BeV25),
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 BeV25 211021.1 N103600 (J2000) 12.3 12.8(CCD) SR
comments:
BeV25: GSC 1108 961
Comparison star was for all measurements GSC 1108 1333 (12.0 mag),
which was checked to be constant.
The change in brightness and the red colour
(USNO A2.0: r:12.4 mag, b:15.5 mag) suggest a SR-variable.
