MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in Blagoveschensk was pointed to the GRB170202.77 37 sec after
notice time and 49 sec after trigger time at 2017-02-02 18:28:58 UT. On
our first (10s exposure) set we found 1 optical transient within SWIFT
error-box (ra=152.525 dec=5.00139 r=0.05) brighter then 16.5
RA, DEC = 10h 10m 03s.5 , + 5d 0m 41s.8
Mag = 16.2
MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in Tunka was pointed to the GRB170202.77 69 sec after notice time
and 85 sec after trigger time at 2017-02-02 18:29:33 UT. On our first (20s
exposure) set we found optical transient within SWIFT error-box
(ra=152.525 dec=5.00111 r=0.05) brighter then 17.8.
MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in SAAO was pointed to the GRB170202.77 4070 sec after notice
time and 4082 sec after trigger time at 2017-02-02 19:36:11 UT. On our
18-th (180s exposure) set we found optical transient within SWIFT
error-box (ra=152.525 dec=5.00111 r=0.05) brighter then 17.00.
