I now have single data points from 5 nights on this variable.
The values are:
HJD V B-V V-R R-I errors
51722.6572 16.067 -0.024 0.036 0.150 0.008 0.011 0.015 0.025

These are interesting values. Obviously, on the first night I caught
the CV on decline from outburst; it was still quite blue. Afterwards,
the 4 nights presumably at quiescence are quite different from one another.
The variable became redder, probably from the companion showing through.
However, (B-V) and (V-R) show unexpected deviations (at least to me).
Perhaps (V-R) is contaminated from H-alpha? What is going on with (B-V)?
Anyone want to venture some guesses? How do the eclipses match with
these times?
