New variable star:
new Brh V131 072245.9 +170228 (J2000) 12.5-13.2 (CCD)

Brh V131: GSC 1351 383
The comparison star is GSC 1351 549 (12.5 mag),
which has been checked for constant brightness.

John Greaves comment:

Johnson B-V as derived from 0.556 * USNO B1.0 B1-R1 is +0.33 (+/- 
0.26), suggesting latest A to early F spectral type.
2MASS J-Ks is +0.15, which equates to F0V (ref: Skiff 
ftp://ftp.lowell.edu/pub/bas/starcats/uvby.calib , section IV)
It is uncertain as to whether this colour is equally applicable to 
F0III and F0I stars though.
The lightcurve suggests a short period variable, with colour and 
probable spectral type suggesting either delta Scutid, RR Lyrae or an 
EW (probably EW/KE) type star. The first is least likely given the 
amplitude of variation, probable period, and a position a little 
distant from the Galactic Plane, but not entirely precluded.

The object is unknown to GCVS, NSV, newvar.cat, SIMBAD, IR 
catalogues, X-ray catalogues, etc.
