SDSS J080434.20+510349.2: variations during the (first) rebrightening

   Kyoto team, Okayama U. of Sci. team, Arto Oksanen and Enrique de Miguel
has reported observations during the rebrightening (rise, maximum and decline).
As already reported, there are clear modulations especially when the system
was faint.  During the early fading branch, there were coherent modulations
(0.06 mag) having a period comparable to either orbital or superhump period.
The nature of these modulations needs to be more closely examined using
more observations (there may be additional rebrightenings).
There were relatively sharp eclipses with a depth of 0.03 mag, indicating
that only a small fraction (spot-like bright portion?) is eclipsed
during the rebrightening.

The variation in this system (during the 2006 superoutburst) was very
complex.  See figures in the following paper for planning your observations!
