OY Car superhumps and eclipses

   Peter Starr has reported that he successfully observed
OY Car for three nights.  Superhumps and eclipses were
well recorded.  Since this object is bright enough,
we can examine the nature of stage B-C transition
(and positive Pdot) using eclipses.  High time-resolution
(10s or less; in HT Cas we obtained good results using
5s exposures) observations are recommended.
