[vsnet-obs 542] Re: Standstill of V344 Lyr?

   Before interpreting this peculiar bahavior of V344 Lyr noticed by
Laszlo Szentasko, it would be useful to mention that V344 Lyr is a
well-established SU UMa-type dwarf nova.  It would be thoeretically
interesting if any standstill-type activity is really observed in SU UMa
systems.
   The following paragraph is taken from the abstract of "Discovery of a
new SU UMa-type dwarf nova V344 Lyrae" in PASJ 45, L67 (T. Kato).

\centerline{\bf Abstract}

  A faint dwarf nova, V344 Lyrae, was observed for five nights in its
long outburst during May--June, 1993.  {\it V}-band CCD photometry revealed
superhumps with a period of 0.09145($\pm0.00002$) day and an amplitude
of 0.3 mag.  This finding confirms V344 Lyrae as being a new member of
SU UMa-type dwarf novae and places it as the second longest
orbital-period dwarf nova below the period gap.  The cycle lengths
of the normal outbursts and superoutbursts have been estimated to be
16$\pm$3 days and 240 days, respectively.
