OT J002656.6+284933: SU UMa-type above the period gap

   Kasai-san has reported observations.  The superhump
period determined from a single night baseline
is 0.133 d (!).  Although this period likely
suffers from a systematic error (the two data sets
did not overlap and there is some uncertainty
in zero-point adjustment), the period is longer
than that of famous TU Men (0.126 d).  This object
probably breaks the longest record of SU UMa-type
superhump period and further observations are
strongly encouraged.
