   The Kyoto team also obtained observation (Ohshima-san, Nakata-san,
Hori-san and Polina Zemko) last night.  The combined data seem to
strengthen this finding.  The measured period is 0.0625(2) d
with double maxima.  The amplitudes were quite low (0.02 mag) and
we need further observations.  Note also this period is longer
than many of those of WZ Sge-type dwarf novae.  The object may be
similar to EG Cnc and should require further attention.
