SDSS J080434.20+510349.2: fading from the second rebrightening, hint of double-wave humps?

   Josch Hambsch has reported most recent observations during the early
fading branch of the second rebrightening.  In addition to eclipses
(almost in phase, 0.02 mag), there were dip-like features around phase
0.4-0.5.  The overall profile is somewhat reminiscent of "double wave"
modulations in WZ Sge-type stars.  This may be either 2:1 excitation
or superposition of superhumps and orbital features.
Continued observations are strongly urged!
