SDSS J080434.20+510349.2: fifth rebrightening, maximum

   Enrique de Miguel has reported observations during the flat portion
of the fifth rebrightening.  Unlike many of past observations, clear
(super)humps with amplitudes of 0.06 mag were observed even at this
maximum phase.  The maxima of the humps were close to the expected
eclipses, which might be responsible for the enhanced hump feature.
The eclipses were also observed immediately following the hump maxima
(relatively sharp drop, depth 0.04 mag).

   Okayama U. of Sci. team has also reported the rising phase of this
rebrightening.  Pavol A. Dubovsky also reported a lot of observations
covering the earlier rebrightenings.  A quick analysis of these data
have confirmed the ealier reports.  More detailed analysis is in progress.
