SW UMa: start of stage B superhumps

   We have received observations from Okayama U. of Sci. team.
The data have confirmed that we are indeed observing stage B superhumps
on Dec. 7 and 8.  The mean period for this interval was 0.05778(1) d,
very close to the period of stage C superhumps in past superoutbursts.
We interpret that we are observing the very early stage of stage B
(period close to stage C superhumps).
