More data here:

Something peculiar is going on. Notice the two weird data points in the 
V band at phase 1.15 or so. The images look perfectly good and don't 
have errors or other indications of bad data. These points go up and 
meet the other night of data. Both nights use the same comp star and 
same everything else. The V band seems to have the same phenomena as 
the Rc band in terms of the light curve being displaced a bit every so 
often. The errors in the comp star magnitudes for the 8/22 data was 
0.002. It was a very steady night. Those two points are way outside 
even 3-sigma. Seen anything like that before?

It is far-fetched speculation at this point, but could this be an 
eclipsing RR Lyr star?
