[vsnet-obs 24340] New variable (BeV30)

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

Dear colleagues!

I would like to send you observations of a new variable star (BeV30),
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 BeV30 233232.6  N103320  (J2000)  12.1 12.4(CCD)

comments:
BeV30: GSC 1172 1452
Comparison star was for all measurements GSC 1172 1385  (11.7 mag),
which was checked to be constant.

Data analysis was made by Chris Lloyd, UK. His comment:
Strong series of periods increasing towards higher frequency. The
best period is 0.2065 days so it may be a beta Cep or delta Sct, or
something similar.
