Re: GSC 4414-1210

FYI, I still only have the one night on this but I redid my photometry 
with Arne's sequence. I got Rc=11.235 with the 1-sigma of the program 
star magnitudes being 0.009. When Arne did his sequence he got 
Rc=11.245. What's interesting is his errors on that star were reported 
as 0.021 but the errors on the next two brightest stars are 0.005 and 
0.001 respectively. I don't know how Arne calculates his errors, but 
this star has higher errors in his sequence than the next 15 or so 
brightest stars. Maybe this means he had some variation in there. It 
seems the previous consensus is that this may have a period around 1.4 
days. So far we have no verification of these 1.0m dips in the TASS 
data but it may be a small amplitude something or other, too.
