    We have performed period analysis using the data kindly sent 
to the Kyoto team.  We calculated a period to be 0.07500(8) d, which 
is slightly shorter than the average superhump period reported 
during the 2000 superoutburst.  This may indicate that the superhump 
period will increase with time from now.  Time-series observations 
are encouraged.

Regards,
Makoto Uemura
