MASTER-Amur ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 349171 ) starts observations of current V404 activity (Swift trigger 668097, S.D.Barthelmy et al. GCN #18716) at 2015-12-23 09:14:02 UT (V.Yurkov et al., GCN #18717 ) just after the sunset .
MASTER-Tunka starts alert observations of V404 at 2015-12-23 10:16:20 UT (just after the sunset, 17447 sec after notice time and 17787 sec after trigger time).
There is fast about half-magnitude variability at the interval about 10min time scale.
