SDSS J080434.20+510349.2: fading stage of the fourth rebrightening

   Enrique de Miguel has reported observations of the fading part of
the fourth rebrightening (Oct. 15).  The humps (superhumps) wer now in
at phase 0.6-0.8 (combined with orbital humps) but with smaller (0.04 mag)
amplitudes.  Eclipses were broad and rather shallow (0.03 mag), but were
comparable to the hump feature.

   Josch Hambsch, in collaboration with Astrokolkhoz team (New Mexico,
Thomas Krajci) and Natalia Katysheva (observed at Crimean Lab. of Sternberg
Astro. Inst.) and Sergey Shugarov (Astronom. Inst. of Slovak) also reported
a lot of earlier observations.  We have re-determined the Pdot of stage B
to be +7.3(1.0)*10^(-5) by incorporating these new data.
