SDSS J080434.20+510349.2: 5th rebrightening and preceding state

   As reported in [vsnet-alert 12279], Maehara-san caught the rising
phase of the fifth rebrightening.  Humps (~0.06 mag) were observed at
binary phase 0.5-0.9 preceded by a likely small dip, and eclipses were
relatively broad and had depths of 0.06 mag.

   Enrique de Miguel and Ian Miller also reported the phase preceding
this rebrightening.  Striking broad humps (phase -0.3-0.2) with
amplitudes 0.27 mag and V-shaped eclipses with depths of 0.17 mag
were clearly observed.
