Dear colleagues!
I would like to send you observations of a new variable star
(Brh V107), 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 Brh V107 061729.2 +090714 (J2000) 11.5-11.9 (CCD)
comments:
Brh V107: GSC 731 2162
The comparison star is GSC 731 2159 (11.7 mag),
which has been checked for constant brightness.
The USNO A2.0 colours (r: 11.4 mag and b: 14.0 mag)
and the following observations suggest a long
period variable, type and period still unknown.
