[vsnet-newvar 1509] New Bernhard variable (Brh V116)

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

Dear colleagues!
 
I would like to send you observations of a new variable star
(Brh V116), 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 V116  173825.5 -034042.4 (J2000) 13.6-13.8 (CCD)
 
comments:
Brh V116: GSC2.2 S220030227697
The comparison star is GSC 5089 320 (13.3 mag),
which has been checked for constant brightness.
The USNO A2.0 magnitudes (r:11.4, b: 14.7) 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?264.6060_-03.6786

These observations confirm the variability of GSC2.2 S220030227697.
