Please observe PNV J20205397+2508145

   There have been no recent time-series photometry
of PNV J20205397+2508145.  Our experience tells that
transition to stage A superhumps (*most important moment*)
tends to occur when people lose interest (when amplitudes
of early superhumps decrease = the 2:1 resonance weakens,
this momemt is theoretically most interesting).
We have missed stage A superhumps in several recent
WZ Sge-type dwarf novae for this reason.  Please keep
intensive time-series observations *just now*.

   If you are interested in astrophysically more important
observations, you can schedule epochs of most intensive
time-series observations just when stage A superhumps
are expected.

   As usual, please ensure to send a copy of observatios
to Isogai-san (isogai at kusastro.kyoto-u.ac.jp).
