[vsnet-alert 16754] MASTER OT J020108.88+504815.6 outburst

[Denis Denisenko]

This dwarf nova in Perseus (originally reported as possible Supernova
in ATel #4509 on 2012 Oct. 22, but spectroscopically identified as a
CV in ATel #4519) was detected in outburst again by Pavel Balanutsa
who had also found it back in 2012.

This outburst is brighter than the discovery one, so the range of the
variability listed in AAVSO VSX (17.8 - 19.9: CR) can obviously be
widened at least up to 16.8 CR (was 17.0 CR when I started writing
this message). Actually, the star at quiescence is about 21m on
Palomar plates, but VSX is listing the minimum magnitudes from MASTER
reference images as reported formally in discovery ATels.

Coordinates (average of 6 measurements on 2014 Jan. 03): 02 01 08.80 +50 48 15.2
