   We have received further data from bservatory and Planetarium of Johann
Palisa, Ostrava team (T. Hynek and R. Kocian, three nights), Okayama
U. of Sci team (two nights), Jani Virtanen, Nakajima-san (two nights),
Michael Richmond, and Kyoto team.

    Up to early Sep. 11, the amplitudes of early superhumps steadily
decreased.  The most recent observation (late Sep. 11) by Nakajima-san
suggest the emergence of ordinary superhumps with an amplitude of
about 0.1 mag.  Due to the faintness of the object and interference
by the Moon, this identification needs to be confirmed by independent
observation.  Since this would signify a drastic change in the behavior
of the object, urgent photometric observations are strongly requested.
