SDSS J160501.35+203056.9: possible superhumps

   Kiyota-san (and earlier by the Kyoto team) have reported observations.
The object is still in bright state, and is better observable
in the morning sky.

   Kiyota-san's recent data probably suggest the presence of 0.2 mag
superhumps, although it is very difficult to determine the period
due to the short visibility.  Observations at other longitudes are
highly encouraged!

  YYYYMMDD(UT)   mag  observer
  20101121.367  120C  (K. Itagaki)
  20101125.735  130C  (Ian Miller)
  20101201.847  13.64C  (Seiichiro Kiyota)
  20101203.841  13.69C  (Seiichiro Kiyota)
  20101204.843  13.85C  (Seiichiro Kiyota)

   As judged from the light curve, the initial faster fading (November)
corresponded to a stage with early superhumps of a WZ Sge-type outburst.
