Dear colleagues!
I would like to send you observations of a new variable star (Brh V75),
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 V75 170222.6 +041027 (J2000) 11.0 11.4 (CCD) SR?
comments:
Brh V75: GSC 406 1063
The comparison star is GSC 406 887 (12.1 mag),
which has been checked for constant brightness.
The apparently slow change of brightness suggests
a SR-variable.
The USNO A2.0 magnitudes (r: 10.9, b: 13.2) have the remark
"magnitudes are probably wrong".
