HS0417+7445 variation of superhump period

   Akazawa-san (Okayama U. of Sci. team) has reported further observations.
After the initial stage A-B transition, the object now show stage B superhumps
with a mean period of 0.07843(4) d.  There seems to be an indication of
a positive period derivative, which is relatively rare at this superhump
period.  Further observations are needed to confirm this period variation.
