[vsnet-newvar 1495] GSC 0396 1222 may be an EA eclipsing binary

[jg <jg@jgws.freeisp.co.uk>]

Preliminary photometric "open source" data from Tom Droege's Mk IV TASS
camera suggests that GSC 0369 1222 may be an EA type eclipsing binary.

On four nights of observation there were three where the star remained
at magnitude around V 11.8 whilst on the other night it was at V 12.9. 
V-Ic also "reddened" by around +0.4.

A nearby star (7' distant) remained around V 12.2 on the same 4 nights
according to the same data, precluding external factors.

The putative eclipse occured around JD 2452426.8, but with only an
hour's worth of observation little morphological detail is evident in
the lightcurve.


With no indication as to period and any possible eclipse having an
amplitude of at least a magnitude, this is a good candidate for visual
monitoring regimes.  Another eclipse or three would allow a preliminary
period to be guesstimated.  The object is currently at a useful hour
angle for observation.  No evidence of known variability can be found in
the standard catalogues nor in the large number of non-standard ones
also checked.

Cheers
