[vsnet-outburst 7038] SDSSp J230351.64+010651.0 strong 0.07-d modulations on Sep. 1

[Taichi Kato]

   Kyoto observations have revealed that SDSSp J230351.64+010651.0 
showed strong 0.4-mag modulations on September 1, during the
decline stage of the recent outburst.  Although the coverage
is insufficient to determine the accurate periodicity, the recorded
period was close to 0.07 d (consistent with the claimed 100 min
periodicity).  The mean light curve had hump-like, rather than
sinusoidal, features.  The object had faded by 1.2 mag/d since
August 31, and further showed a much slower decline during the
subsequent nights.  The initial fading rate is consistent with
what could be expected for a normal outburst of a 100-min dwarf
nova.

   The presence of strong modulations following a short outburst
resembles that of BZ UMa, a short-period system without recorded
superoutbursts.
