[vsnet-alert 15172] MASTER OT J042609.34+354144.8 going into outburst

[Denis Denisenko]

This CV in CPM pair and the brightest optical transient discovered by
MASTER so far (see ATel 4441 and [vsnet-alert 14965]) has brightened
by the whole magnitude since the last night, according to observations
with Bradford Robotic Telescope:

MASTER OT J042609.34+354144.8
  20121215.085  16.82  BRT
  20121216.074  15.89  BRT

(AAVSO sequence was used with V=12.72 for 127 comparison star).

The previous (discovery) outburst in late September - early October
was a superoutburst. Already well developed superhumps were detected
on Oct. 2 [vsnet-alert 14970]. The period over the following week was
measured as 0.0676-0.0673d, see also [vsnet-alert 14979] and
[vsnet-alert 14989].

It will be very interesting to see how this new outburst develops!
Also, since the previous outburst peak was likely missed by a few
days, the star may be brighter than 12.6 at maximum. Observations are
encouraged!
