[vsnet-newvar 1512] New Bernhard variable (Brh V118)

["Klaus Bernhard" <kl.bernhard@aon.at>]

Dear colleagues!
 
I would like to send you observations of a new variable star
(Brh V118), 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 V118 164243.4  -033401.1 (J2000) 12.4-12.6 (CCD)
 
comments:
Brh V118: GSC 5053 989
The comparison star is GSC 5053 935 (11.15 mag),
which has been checked for constant brightness.
The  USNO A2.0 magnitudes (r:11.9, b: 14.7) and
the following observations suggest a long period variable,
type and period still unknown.
