[vsnet-newvar 1521] New Bernhard variable (Brh V120)

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

Dear colleagues!

I would like to send you observations of a new variable star
(Brh V120), 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 V120  184705.5 -033145.3  (J2000) 12.7-12.9 (CCD)

comments:
Brh V120:  GSC 5118  427
The comparison star is GSC 5122  294 (12.2 mag),
which has been checked for constant brightness.
The  USNO A2.0 magnitudes (r:10.8, b: 14.6) 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_curve2.cgi?281.7733_-03.5295

These observations (especially I-band) confirm the variability of GSC 5118
427.
