[vsnet-alert 8683] OT_J195951.3+224232 = Var Vul 05, analysis of the current rebrightening

[Taichi Kato]

   As judged from the recent behavior of  OT_J195951.3+224232
= Var Vul 05 (new CV near M27), the recent rebrightening may
be a short one (normal outburst).

   The behavior of rebrightenings in WZ Sge-type dwarf novae
is different from one object to another.  This seemingly
short duration of the rebrightening may either suggest that
it would trigger a next outburst (as in AL Com 1995) or
a part of repeated short rebrightenings as in WZ Sge 2001,
or more seperated repeated normal outbursts as in EG Cnc.

"The 1995 Superoutburst of the WZ Sagittae-Type Dwarf Nova AL Comae Berenices"

  Please have a look at the complex light curve in AL Com
following the "dip".  The early part of the rising stage was
recorded by amateur observers (was actually from cover page
photographs on "The Astronomer").  This was probably the first
case in which amateur observations played a cruicial role
in observing WZ Sge-type dwarf novae.
