   Itoh-san's latest observation on June 8 recorded 0.1-mag
superhumps.  The period was ~0.06 d (or may be slightly longer).
Since these are expected to be stage A superhumps, further
observations are very strongly encouraged!

   The observers and groups who have contributed up to now
are: Enrique de Moguel, Arto Oksanen, Josch Hambsch,
Kyoto U. team, Osaka Kyoiku U. team, Maeda-san, 
Rochester Institute of Technology team, Shiokawa-san and
Itoh-san.  The data up to June 7 did not show detectable
superhumps.
