OT J122221.6-311525: longer period?

   We have received further observations from Josch Hambsch
and Kiyota-san.  The new data seem to show a longer period.
If we restrict analysis to the data after Jan. 12, we obtained
a period of 0.09077(9) d, which expresses the moments of
maxima fairly well, while the earlier value apparently fails
to express them.  This period was not detected in the earlier
observations.  Since none of WZ Sge-type dwarf novae showed
such a long period, further observations are extremely encouraged.
