V466 And: period evolution!

   We have received further data from Etienne Morelle (two nights),
Tim Crawford and Kyoto observations.

   As expected in the preceding announcement, the superhump period showed
a distinct transition from a longer (during the evolutionary stage) to
a more stable one.  This transition took place on Sep. 14.  The period
after the transition (likely the representative superhump period
of this system) is 0.05706(5) d.  The fractional superhump excess is
1.2%, which is now typical for a WZ Sge-type dwarf nova.
Further continuous observations are strongly encouraged!
