[vsnet-alert 2237] V419 Lyr superoutburst

V419 Lyr superoutburst

  According to Pietz's observations (vsnet-obs 15708,
  http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/Mail/obs15000/msg00708.html),
the long-period SU UMa star V419 Lyr is definitely in superoutbrust.
The object being in declining stage, any intended time-resolved photometry
should be an urgent task.  The likely supercycle length inferred from
previous observations is around 300-400 days.
