[vsnet-newvar 1511] New Bernhard variable (Brh V117)

Dear colleagues!

I would like to send you observations of a new variable star
(Brh V117), 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 V117 184231.48 -033539.6 (J2000) 12.5-12.8 (CCD)

comments:
Brh V117: GSC 2.2 S300313115612
The comparison star is GSC 5117 2186 (12.6 mag),
which has been checked for constant brightness.
The GSC 2.2 magnitudes (r:11.7, b: 15.2) and
the following observations suggest a long period variable,
type and period still unknown.

Vizier investigations show that further photometry
for this object can be found via the TASS Mk III tenxcat
database at:

http://a188-l009.rit.edu/cgi-bin/tass_curve.cgi?11945383_280.6312_-3.5943

These observations confirm the variability of this
object.
