[vsnet-alert 15076] CSS 090426:064659+483051 outburst

[Denis Denisenko]

MASTER-Tunka robotic telescope has detected an outburst of this dwarf
nova in Auriga on survey images (180-sec exposures) from the last
night:

CSS 090426:064659+483051
  20121030.864  16.28+/-0.13 V  MASTER-Tunka
  20121030.901  16.81+/-0.18 V  MASTER-Tunka
  20121030.903  16.39+/-0.13 V  MASTER-Tunka
  20121030.906  16.18+/-0.13 V  MASTER-Tunka

Variability range is given as 17.0-19.8 in AAVSO VSX.

Previous outburst detected by MASTER-Tunka was on 2012 Apr. 07 (to
16.3-16.1 CR).

The large amplitude of fast variability (0.6+/-0.2m) appears to be
real, so this CV may be an eclipsing dwarf nova.
