MASTER-SAAO robotic telescope (MASTER-Net: http://observ.pereplet.ru) located
in SAAO was starting survey on the LAT GRB170510.22 error-box (Bissaldi et
al., GCN #21080) 22480 sec after notice time and 41530 sec after trigger time
at 2017-05-10 16:44:36 UT. The 5-sigma upper limit on our first (180s exposure)
set is about 18.9 mag
We marginaly see optical candidate (Cucchiara et al. GCN 21087) at XRT
(Evans et al. GCN #21082, Melandri et al. GCN #21086) position with
unfiltered mag ~ 19 m .
Ra, Dec = 10 40 36.76 -39 12 43.8 (+/-1 arcsec)
We did not see object 2.5 hours late with limit 19.5 .
So X-ray Source 1 (Melandri et al. GCN #21086) is possible OT.
