[vsnet-obs 23861] New variable (BeV21)

["Klaus Bernhard" <klaus.bernhard@vpn.at>]

Dear colleagues!

I would like to send you observations of a new variable star (BeV21),
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 BeV21 195412.7   N103928  (J2000)  12.2 12.5(CCD) SR

comments:
BeV21: GSC 1062 2668.
Comparison star was for all measurements GSC 1062 555  (11.4 mag),
which was checked to be constant.
The change in brightness and the red colour
(USNO A2.0: r:12.4 mag, b:15.2 mag) suggest a SR-variable.
