MASTER-Kislovodsk robotic telescope (MASTER-Net: 
http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, 
vol. 2010, 30L) located in Russia (Lomonosov MSU, Kislovodsk Solar Station 
of Pulkovo observatory) was starting survey on the IPN  GRB181011.15 
error-box (K. Hurley et al GCN 23328)  33218 sec after notice time and 
61888 sec after trigger time at 2018-10-11 20:47:47 UT. The 5-sigma upper 
limit on our images is about 19 mag.


MASTER-Tavrida robotic telescope  located in 
Russia (Lomonosov MSU, SAI Crimea astronomical station) was starting 
survey on the IPN  GRB181011.15 error-box  45716 sec after notice time and 
74386 sec after trigger time at 2018-10-12 00:16:05 UT. The 5-sigma upper 
limit on our images is about 19 mag.

MASTER-Net cover full IPN (K. Hurley et al. GCN 23328) and MAXI (Kawakubo 
et al. GCN 23327)  error boxes.
