MASTER-Tunka robotic telescope (MASTER-Net: http://observ.pereplet.ru,
Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located near
Bykal Lake (Irkutsk University Astrophysical Center) was starting survey
on the FERMI GRB180914.52 error-box (Poolakkil et al., GCN #23227).
17768 sec after trigger time at
2018-09-14 17:27:55 UT. The 5-sigma upper limit on our first (180s
exposure) set is about 16.0 mag
No OT found.
MASTER-SAAO robotic telescope (MASTER-Net: http://observ.pereplet.ru,
Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in
South Africa (South African Astronomical Observatory) was starting survey
on the LAT GRB180914.52 error-box (ra=03 30
57 dec=-05 15 35 r=0.4, (Bissaldi et al., GCN #23225)).
15521 sec after notice time and 38331 sec after trigger time at 2018-09-14
23:10:38 UT. The 5-sigma upper limit on our first (180s exposure) set is
about 18.5 mag
The cover map is available at

No new objects brighter than 18.5 mag were found after the human analysis
of automatic candidates.
====================================================================
The galacitc latitude b = 0 deg.
The observations made on zenit distance = 54 deg.The moon (31 % bright
part) below the horizon (The altitude of the Moon is -19 deg. ).
The sun altitude is -59.4 deg.
The object can be observed till sunrise at 2018-09-15 04:35:52
