V466 And superhump period update

   We have received new data from Michael Richmond.  V466 And still
clearly show superhumps.  The best superhump period (disregarding its
early evolutionary stage) up to now is 0.057073(9) d.
The period derivative Pdot/P is almost exactly zero, +0.4(1.2)*10^(-5),
which shares the common property with most extreme WZ Sge-type dwarf
novae, such as WZ Sge and V455 And.  In combination with the long-lasting
stage of early superhumps, V466 And would be very analogous to WZ Sge
and may be expected to show varieties of late-stage phenomena such as
repetitive rebrightenings.  Further intensive observations are very
strongly encouraged!
