Tlatov, V.Senik, A.V. Parhomenko, D. Dormidontov Kislovodsk Solar Station of the Pulkovo Observatory D.Buckley, S. Potter, A.Kniazev, M.Kotze South African Astronomical Observatory MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru) located in IAC was pointed to the GRB170728B (Cenko et al., GCN Circ. #21371) 28 sec after notice time and 39 sec after trigger time at 2017-07-28 23:04:01 UT. On our first (10s exposure) set we found optical transient within SWIFT XRT error-box ( D'Elia et al., GCN #21376; ) in two polarizations! The 5-sigma upper limit has been about 16.9 mag We 100% found faiding OT on first 10 minutes images with m ~ 16.5 up to 18 mag. RA, DEC = 15h 51m 55s.5 , +70d 7m 19s.3 Error = +- 1.4 arcsec The faiding OT may be coincide with D'Avanzo et al. position (GCN #21372) and Heintz et al., (GCN #21374) and Izzo et al., (GCN #21381) and The observations made on zenit distance = 47 degrees, galaxy latitude b = 40 degree. The moon (34 % bright part) is 8 degrees above the horizon. The distance between moon and object is 78 The sun altitude is -33.7 degree. The error box can be observed till sunrise at 2017-07-29 06:25:17. The message may be cited.
