  Nakajima-san's simultaneous two-color time-series photometry of
V455 And has clearly detected marked reddening during the current
apparent "dip" phase.  The data seem to suggest the significant
contribution of the cool component to the accretion disk.
This cool component may be responsible for WZ Sge-type dip or
rebrightenings.

   Sep. 18  +0.20

   Sep. 22  +0.26
   Sep. 25  +0.62

  The light curve shows rich structure, which will be duly
reviewed by Maehara-san in combination with other reported
time-series data.

  Continued observations are still very wanted.
