SW UMa: growth of superhumps

   Akazawa-san (Okayama U. of Sci. team) reported further observations.
The data on Dec. 5 and 7 show growing superhumps (stage A).
The amplitudes on Dec. 5 were ~0.10 mag and 0.17-0.24 mag on Dec. 7.
The O-C diagram shows stage A period evolution (period longer than
typical stage B periods).  A stage A-B transition may have
occurred on Dec. 6.
