OT J122221.6-311525: longer period

   The object only slightly faded.  Josch Hambsch's data
clearly show modulations with 0.2-0.3 mag.  A period based
on two consecutive nights was 0.0770(1) d, longer than
the previous superhump period.  Observations of the subsequent
stage is very important considering the strength of
the superhump signal.
