SDSS J080434.20+510349.2: post-fifth rebrightening

   Ian Miller and Enrique de Miguel have reported further observations.
The object did not enter a new rebrightening on Oct. 21 (a very slight
rising trend may have been present).  The fading rate between rebrightenings
has been almost constant, suggesting that the present state of activity
is still persisting.  It may be that the interval between rebrightenings
may be getting longer.

   On Oct. 21, the object showed double-wave modulations (full amplitudes
0.3 mag).  One of the minima roughly corresponds to eclipses, but occurred
significantly later.  The two humps may be attributed to orbital humps
and superhumps.  Further continued observations are encouraged!
