MASTER-SAAO robotic telescope (MASTER-Net: http://observ.pereplet.ru Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) ,
located in South African Astronomical Observatory,
was pointed to the Swift GRB180705A (BAT: Stamatikos et al. GCN 22902, GRBtime: 2018-07-05 15:41:14UT; XRT : RA,Dec2000=14h 10m 27.18s -11d 38' 54.3" Kennea et al. GCN22903)
at 2018-07-05 15:54:52 ( GRB Altitude: 55.90, Sun: Altitude: -3.10) at sunset.
So MASTER-SAAO started GRB180705A observations at 2018-07-05 16:35:54UT (GRB altitute: 62.78, Sun: Altitude: -11.10).
MASTER automatic unfiltered (W=0.2B+0.8R by USNO-B1) limits are the following
