Dear colleagues!
I would like to send you observations of a new variable star (BeV35),
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 BeV35 051722.0 N101828 (2000) 12.5 12.9 (CCD)
comments:
BeV35: GSC 703 1930
Comparison star was for all measurements GSC 703 2180 (12.2 mag),
which was checked to be constant.
Data analysis was made by Chris Lloyd, UK.
His comment:
GSC 703.1930 has a very strong series of frequencies at n.417
cycles/day.
Marginally the best is 0.41376 days (f=2.417), but the variation is very
sinusoidal and for most the error is very small, about 0.01 mag. It may
be a c-type RR Lyrae variable or perhaps an ellipsoidal variable.
