The Kyoto team obtained 5 hours light curve during the
last night (February 26) observation. Superhumps are still
prominent. Their amplitude is about 0.25mag.
Using our combined data set except for the very early phase on
February 18 and 19, the PDM period analysis yields a superhump
period of 0.06504 day. This is slightly longer than previously
reported in [vsnet-campaign 795] using February 20 - 24 data.
The object has gradually faded with a rate of 0.13 mag/d since
February 18, but there are significant differences on this
monotonous decline trend, which may related to the beat phenomenon.
The superoutburst is now ongoing. More time-series observations
are urged.

Makoto Uemura
