[vsnet-alert 9612] V455 And rapid fading, likely a WZ Sge-type dip phenomenon

[Taichi Kato]

   V455 And rapid fading!  The initial rapid fade seems to have
stopped.  The current phenomenon is thus likely a "dip" seen
in WZ Sge-type superoutbursts.

   Orbital (eclipse) and superhump light variation became complex 
during and after this stage of the 2001 WZ Sge outburst.

  (see esp. messages vsnet-alert 6288, 6293 and later)

   Detailed observations are thus highly wanted!
