SDSS J080434.20+510349.2: post-sixth rebrightening

   We have received further observations from A. Baklanov (Crimean
Astroph. Obs., via E. Pavlenko) for two nights during this stage.
An analysis of the combined data has generally confirmed the earlier
reports, but with better statistics.  On Oct. 24, the maxima of humps
(full amplitudes 0.20 mag) were near the predicted eclipses.  There was
little evidence for a sharp eclipse, but a shallow dip following the
hump maximum may be attributed to a broad eclipse feature.
On Oct. 25, the phase of humps has advanced (indicating the superhump
nature).  The full amplitude was 0.14 mag and ther profile was structured
with multiple maxima (or associated with shallow dip-like features).

   We have also received a large number of data from S. Shugarov
(Slovakia), during the plateau and subsequent stages -- the most recent
one being the rising phase of the sixth rebrightening.
We have also received observations from Arto Oksanen, who observed
the early fading stage of the sixth rebrightening.
