   We have received these observations and confirmed the basic feature.
Ian Miller also reported observations on the previous night.
It is most likely that the 0.047 d period observed at the early stage
was double-wave "stage A" superhumps, which have longer periods than
those of ordinary superhumps.
While the V485 Cen or EI Psc-type classification is now invalidated,
the strong appearance of TiO feature at this superhump period is
still unusual.  This object somewhat reminds me of QZ Ser, a dwarf nova
with a similar period and with a luminous secondary.

   Further continued observations are encouraged!
