MASTER-IAC robotic telescope (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 Swift GRB181003A (Beardmore et al. GCN 23295, Evans et al. GCN 23296)
4 sec after notice time and 59 sec after trigger time at 2018-10-03 05:12:02 UT, with
upper limit up to 19.1 mag.
The observations started on zenit distance = 65 deg.
The sun altitude was -23.8 deg.
MASTER-OAFA robotic telescope located in Argentina (OAFA observatory of San Juan National University)
was pointed to the GRB181003A
10 sec after notice time and 64 sec after trigger time at 2018-10-03 05:12:08 UT,
with upper limit up to 20.3 mag.
The observations started on zenit distance = 27 deg.
The sun altitude was -53.3 deg.
The galactic latitude b = -60 deg., longitude l = 98 deg.
We obtained the following upper limits:
