OU Vir: superhumps
Observations by Kyoto U. team on Mar. 8 detected clear superhumps (and of course eclipses). Superhumps were not apparent on Mar. 6 (Itoh-san). It looks like that these observations and Tordai's data on Mar. 5 corresponded to the precursor. We have also received data from Tordai on Mar. 7, which will be analyzed in due time.
