[vsnet-newvar 548] New Bernhard variable (BeV57)

[Klaus Bernhard <kl.bernhard@aon.at>]

Dear colleagues!

I would like to send you observations of a new variable star (BeV57),
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 BeV57 202239.1 +040940.2  (J2000) 11.6 11.9 (CCD) SR

comments:
BeV57: GSC 505 1725
Comparison star was for all measurements GSC 505 460  (11.7 mag),
which was checked to be constant.
The apparently slow change in brightness and the red colour 
(USNO A2.0 r:11.1 mag, b:13.5 mag) suggest a SR-variable.
