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 detected new optical
object (Lipunov et al., GCN Circ #23048) MASTER OT J165415.75-540239.27
at Swift XRT position (Starling et al., GCN
#23046; Perri et al., GCN #23049;):
RA, DEC = 16h 54m 15.75s , -54d 02m 39.27s
Error ~1 arcsec
We see a gradual attenuation of the OT on an automatic light
curve. Thus, the transient is an optical counterpart of the gamma-ray
burst GRB 180728A.
The automatic light curve is available at
