MASTER-OAFA robotic telescope (MASTER-Net: http://observ.pereplet.ru,
Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in
Argentina (OAFA observatory of San Juan National University) was pointed
to the GRB180722A( Shimomukai et al., MAXI/GSC detection, GCN #23005)
17 sec after notice time and 2572 sec after trigger time at 2018-07-22
06:42:08 UT. On our first (180s exposure) set we not found optical
transient within MAXI error-box (ra=302.613 dec=24.2364 r=1) brighter
then 17.7.
The observations made on zenit distance = 62 degrees, galaxy latitude b =
-5 degrees.
The moon (74 % bright part) is 4 degrees above the horizon. The distance
between moon and object is 75 .
The sun altitude is -61.0 degree.
The object can be observed till 2018-07-22 09:45:34.
