1RXS J023238.8-371812 superhumps update

   We have received further data from Kiyota-san.  Recent data
sets now confirm that the mean superhump period is systematically
shorter than the previous estimate.  The mean period determined
from observations since Oct 5 is 0.06614(2) d.  There was likely
a rapid period change during the early stage of superhump
evolution.  Such behavior is relatively frequently seen in
usual SU UMa-type dwarf nova during the early development stage
(usually within a few days following the maximum), but the preceding
long-lasting early bright state in this object is a mystery.
