Dear colleagues!
I would like to send you observations of a new variable star
(Brh V109), 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 V109 071817.8 +085729.8 (J2000) 11.1-11.6 (CCD)
comments:
Brh V109: GSC 763 58
The comparison star is GSC 763 784 (11.9 mag),
which has been checked for constant brightness.
The USNO A2.0 colours (r: 11.4 mag and b: 13.9 mag)
and the following observations suggest a long
period variable, type and period still unknown.
