[vsnet-alert 13994] Possible DDE 19 outburst

[Denis Denisenko]

The dwarf nova in Cepheus DDE 19 (magnitude range 14.9-18.7R, see
[vsnet-alert 13874] for more info) appears to be going into outburst
again, as shown by the observations with 40-cm Djigit telescope of
Ka-Dar observatory's TAU station (remotely by V. Gerke):

  20111205.663  18.5C  TAU, Ka-Dar
  20111219.953  18.0C  TAU, Ka-Dar
  20111222.771  17.1C  TAU, Ka-Dar

The confirmation is encouraged! The previous outburst a month ago
(Nov. 20-24) turned out to be a superoutburst with the period of
0.091d (almost exactly 11 cycles per day) measured from observations
by Bill Stein. See [vsnet-alert 13886], [vsnet-alert 13890] and
[vsnet-alert 13896].
