MASTER-IAC robotic telescope (4 square degreess,Global MASTER-Net:
http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy,
vol. 2010, 30L) located in Spain (IAC Teide Observatory) was pointed to
the GRB181222B 107 sec after trigger time
at 2018-12-22 20:13 24 UT in two polarizations. On our first ( 20s
exposure ) set we not found optical transient within FERMI error-box (ra=311.146 dec=22.8597 r=1.6)
The real time cover map is available

====================================================================
The galactic latitude b = -13 deg., longitude l = 67 deg.
The observations made on zenit distance = 62 deg.The moon (100 % bright
part) is 25 deg. above the horizon. The distance between moon and object
is 122
The sun altitude is -27.2 deg.
The object can be observed till sunrise at 2018-12-23 07:52:51
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 starting survey on the FERMI GRB181222B error-box (20
44 35 dec=+22 51 36, r=1.6) 45931 sec after notice time and 46503 sec
after trigger time at 2018-12-23 09:06:40 UT. The 5-sigma upper limit on
our first (60s exposure) set is about 16.5 mag
