7400 cycles since early observations.
s.e. of period is 0.0012 from those obsns.
Accumulates to 9 days or 2 cycles by now.
From new obsns, s.e. presently 0.00039.
P/7400 is about 0.0006 days, so we need +/-.0002.
Current uncertainty is 2.8 days, but it would be unfortunate if the 
actual error were 4 days rather than 1/2 as it appears to be now.
Will take till next season to get an accurate-enough period.
