Dear colleagues!
I would like to send you observations of a new variable star (BeV38),
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 BeV38 060520.1 N100425 (J2000) 11.6 12.1(CCD)
comments:
BeV38: GSC 721 2377
Comparison star was for all measurements GSC 721 2390 (12.0 mag),
which was checked to be constant.
Data analysis was made by Chris Lloyd, UK. His comment:
GSC721.2377 looks like an eclipsing binary and four possible periods
emerge at 0.365, 0.636, 1.363 and 1.634 cycles/day.
These are 2.74, 1.57, 0.73 and 0.61 days, but the real period may be
twice any of these, although I would guess it's in the 1 - 2 day
range.
