Dear colleagues!
I would like to send you observations of a new variable star (BeV28),
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 BeV28 212830.2 N104522 (J2000) 12.7 13.2(CCD)
comments:
BeV28: GSC 1123 1704
Comparison star was for all measurements GSC 1123 1430 (12.8 mag),
which was checked to be constant.
Data analysis was made by Chris Lloyd, UK. His comment:
Very clear series of periods at 1.76 days and its 1-day aliases.
Best period looks like 0.636 days and this one also could be eclipsing,
so the true period could be 1.28 days.
