    B. Monard again got data sets of this object for 
4 nights.  Great work, Berto!!  

    Superhumps now have sharper peaks.  The last two-night data 
show a possible sign of secondary peaks after main humps.  
Superhump amplitudes are ~0.15 mag, and show no large variation. 
The average fading rate is 0.12 mag/d.  We will try to detailed 
period analysis in the next couple of days.

    Time-series observations are very important in order to catch 
the evolution of an accretion disk associated with potential 
dramatic variations in near future.
