[vsnet-chat 3374] RX J1450.5+6403

[aah@nofs.navy.mil]

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
51726.7618 17.105  0.044  0.272  0.408   0.011  0.014  0.018  0.024
51727.7987 17.734 -0.144  0.294  0.350   0.020  0.023  0.038  0.059
51730.7121 17.474  0.259  0.276  0.396   0.009  0.011  0.015  0.022
51731.7038 17.707 -0.206  0.558  0.218   0.009  0.011  0.013  0.017

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?
