[vsnet-newvar 2137] GSC 396-1222 is a long period EA



Originally found by John Greaves in Tom Droege's data, GSC 396-1222
proved to be a long period EA type eclipsing binary from TASS
(http://vsnet.tass-survey.org) and ASAS3 data (Pojmanski, G.
2002AcA....52..397P, http://archive.princeton.edu/~asas/).  The
following ephemeris fits the data until now:
JDMin=2452426.75 + 26.989 E 

Magnitude V=11.8-13.1, V-Ic=0.88, duration of eclipse less than 44
hours.
There is still a slight possibility that the actual period is half the
given value.  In that case the eclipse takes less than 14 hours.  A
secondary eclipse has not yet been positively identified.
