PR Her early superhumps

   We have received further data from Akazawa-san, Okayama U. of Sci. team,
Osaka Kyoiku U. team, Enrique de Miguel and Seikei High School team.

   According to the data, the mean period of early superhumps
has been 0.05423(3) d.  The profile before Nov. 25 has been typical
of early superhumps (full amplitude 0.10 mag), but the primary peak
has become stronger since Nov. 25, and the full amplitude decreased
to 0.07 mag.  This might be an indication of emerging ordinary
superhumps.  Observations are encouraged!
