   Itoh-san and Tamas Tordai have also reported
observations.  The period of early superhumps has been
updated to be 0.0619(1) d.  The amplitudes of
early superhumps are large enough.

   This period suggests that this object would
belong to WZ Sge stars with multiple rebrightenings.
Determination of the mass ratios in such systems
by detecting stage A superhumps is very desirable.

   The very bright outburst in ASAS-3 looks somewhat
a mystery to me.
