GSC 3493-1324

Patrick Wils, it appears that the period you came up with on this star  
is broken now that TASS got some more data. It also doesn't work with  
the data I got the last couple of nights. In two nights I got one that  
showed no variation over 5 hours and one that showed a 0.4 mag drop in  
V over 2.5 hours. I almost got the ToM but clouds moved in. I tried  
using AVE and Fourier to find a new period to no avail. One could make  
an educated guess of the ToM from my data as 2453160.7287. That puts  
the ToM's, in a very loose way, at the following:

2452758.7857
2452781.7331
2452785.7228
2453109.8470
2453160.7287

FYI, I'm doing simultaneous V and Rc. The period is long enough on this  
(and clear skies rare enough) that I would be appreciative if anyone  
wanted to grab V data until we figure this guy out. It appears to be a  
detached system and it is possible, even probable, that we have a  
flat-bottomed eclipse.
