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 pointed to 
the  FRB180714 (Oslowski et al., ATel #11851) 35553 sec after notice time and 6 
days 31953 sec after trigger time at 2018-07-20 19:01:16 UT. On our second 
(180s exposure)  set we  not found  optical transient within MASTER error-box 
(ra=266.55 dec=-11.7631 r=0.3) brighter then 17.0.

The observations made on zenit distance = 56 degrees, galaxy latitude b = 8 
degree.
The moon (60 % bright part) is 21 degrees above the horizon. The distance 
between  moon and  object is 47
The sun  altitude  is -19.1 degree.
The object can be observed till 2018-07-21 00:17:55


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 pointed to the FRB 180714.42 39278 
sec after notice time and 6 days 35678 sec after trigger time at 2018-07-20 
20:03:21 UT. On our first (180s exposure)  set we not  found optical transient 
within FRB error-box (ra=266.55 dec=-11.7631 r=0.3) brighter then 19.1.

The observations made on zenit distance = 21 degrees, galaxy latitude b = 8 
degree.
The moon (61 % bright part) is 46 degrees above the horizon. The distance 
between  moon and  object is 47
The sun  altitude  is -52.8 degree.
The object can be observed till 2018-07-21 03:00:43.


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 the  FRB180714.42 46969 sec after notice time and 6 
days 43369 sec after trigger time at 2018-07-20 22:11:32 UT. On our first (180s 
exposure)  set we  not found optical transient within Master error-box 
(ra=266.55 dec=-11.7631 r=0.3) brighter then 17.7.


The observations made on zenit distance = 42 degrees, galaxy latitude b = 8 
degree.
The moon (61 % bright part) is 39 degrees above the horizon. The distance 
between  moon and  object is 45
The sun  altitude  is -24.6 degree.
The object can be observed till 2018-07-21 04:33:33.
