SDSS J080434.20+510349.2: fading stage of the third rebrightening

   Josch Hambsch, Enrique de Miguel and Ian Miller have further reported
observations during the fading stage of the third rebrightening.
Modulations with typical amplitudes of 0.05 mag were recorded.
The maximum of the hump occurred at eclipse phase 0.2-0.3, suggesting
that these humps are superhumps.
The eclipse became much shallower and broad (0.01-0.02 mag) on the
rising branch of the humps.
