   As reported by a number of observers, there appears to be an
emerging signal of superhumps.  A preliminary analysis of the
data since Sep 11.5 (data compiled by Maehara-san; the details
and the list of observers will be reviewed in more detail later) has
yielded a period of 0.05726(2) d, which is 1.7% longer than the orbital
period.  The value has a little uncertainty because superhump period
seems to be still developing and the profile is likely contaminated by
the orbital modulation.  Further more elaborate analysis will be
presented by Maehara-san.
