MASTER-OAFA robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in Argentina was pointed to the Swift trigger 810300 (Barthelmy et
al. GCN #22416) 23 sec after notice time and 1742 sec after trigger time
(18/02/16 05:37:23.51UT) at 2018-02-16 06:06:26 UT with unfiltered
mlim=19.1 (5-sigma) on single images, 19.9m on sum(1800s).
There is marginally seen optical source, possibly known 2MASS source
in 1.3" (with known J-K=1) from SWIFT XRT (D'Avanzo et al. GCN #22417)
center
RA (J2000.0) = 16 58 12.58
DEC (J2000.0) = -42 41 55.7
inside 3.83 arcsec error-box (radius, 90% containment).
