Dear colleagues!
 
I would like to send you observations of a new variable star
(Brh V137), which I have discovered in a systematic CCD-based
search for new variables.
In each observing run typically 600 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 V137    20 19 49.6 -12 30 38.2 (J2000) 11.0-11.6 (CCD)
 
comments:
Brh V137: GSC 5749 1622 =HD 193276
The comparison star is GSC 5749 1269 (13.5 mag),
which has been checked for constant brightness.

ASAS3 observations are available at:

John Greaves has kindly sent a comment:
It's HD 193276, and the Michigan HD catalogue says it is F8/G0 V.
It seems very likely to be associated with the bright xray catalogue source 
1RXS J201950.0-123037, with quite good positional agreement.

Without any lightcurve information, I'd guess at another EW star, which'd fit 
with the amplitude, though these usually tend to be faint xray catalogue 
sources, so there is a chance or two of it being something slightly different 
to EW.
