   Maehara-san has reported more data of OT_J163120.9+103134 taken
on May 15.  The most up-to-date refined data set gives a mean superhump
period of 0.06405(1) d.  The analysis of superhump timings now gives
a more usual value of dP/P = -8(3)*10^(-5).  The earlier values for
superhumps and period change may have been affected by the initial
stage of development.  The new value seems to suggest a more usual
SU UMa-type dwarf nova.
