MASTER-Amur robotic telescope (Global MASTER-Net:
http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy,
vol. 2010, 30L) located in Russia (Blagoveshchensk State Pedagogical
University) was pointed to the GRB190106.57 (Swift BAT alert, GCN 23615)
20 sec after notice time and
36 sec after trigger time at 2019-01-06 13:35:20 UT. On our first (10s
exposure) set we found optical transient within SWIFT BAT error-box
(ra=29.8792 dec=23.8567 r=0.05).
The 5-sigma upper limit has been about 16.5mag
RA, DEC = 01h 59m 31.20s +23d 50m 44.04s
mag = 16.0

This optical counterpart is coincident with Swift optical object (Sonbas
et al., GCN 23615).
The galactic latitude b = -36 deg., longitude l = 143 deg.
The observations made on zenit distance = 45 deg.The moon ( 0 % bright
part) below the horizon (The altitude of the Moon is -50 deg. ).
The sun altitude is -53.7 deg.
The object can be observed till 2019-01-07 18:34:53
This message may be cited, but this is the first automatic photometry.
Non monotonic light curve was detected.
