SDSS J080434.20+510349.2: post-fifth rebrightening state, reanalysis of the plaeau phase

   Enrique de Miguel has reported another run during the slow fading branch
following the fifth rebrightening.  The object showed 0.25-mag (super)humps,
which had maxima at phase 0.2-0.5.  There appears to be a dip in the middle
of these humps (depth ~0.13 mag), which are out of phase from eclipses.
The eclipses were also observed (close to the expected epoch) -- relatively
sharp and depths were about 0.1 mag.

   The Terskol team (Maksim Andreev and Nikolai Parakhin) has also reported
a large set of observations during the main superoutburst.  Combined with
the other data, we have obtained a mean Pdot of +7.5(0.8)*10^(-5) for
Sep. 24 - Oct. 2.  The period, however, rather steeply increased near the
end of this segment.  Restricting to Sep. 24 - Oct. 1, we obtained
Pdot = +4.5(0.6)*10^(-5), which might be a better representative value
of the current superoutburst.
