Dear colleagues!
I would like to send you observations of a new variable star (BeV45),
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 BeV45 163532.6 +035940.3 (J2000) 12.2 12.7(CCD) SR
comments:
BeV45: GSC 390 1871
Comparison star was for all measurements GSC 390 2218 (12.5 mag),
which was checked to be constant.
The slowly change in brightness and the red colour
(USNO A2.0 r:13.2 mag, b:17.2 mag) suggest a SR-variable.
The relatively large scatter in the observing data
is likely due to slightly different
observing conditions and the b-r=4.0 (clear larger than
of available comparison stars).
