SDSS J133941.11+484727.5: fully grown superhumps

   Maehara-san and Gianluca Masi have reported new observations.
The data show fully grown superhumps (amplitudes 0.18 mag).
The period has become somewhat stabilized since Feb. 13
and the mean period has been 0.05853(8) d, 2.1% longer than
the orbital period.  This fractional period excess is large for
a WZ Sge-type dwarf nova, and the period might further shorten
during the present evolution of superhumps.
