MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in Kislovodsk was pointed to the GRB140108A 22 sec after notice
time and 39 sec after trigger time at 2014-01-08 17:19:21.913 UT in two
polarizations. On our first (10s exposure) set we haven`t found optical
transient within SWIFT error-box ( Racusin et al. GCN 15699 ).
The 5-sigma upper limit has been about 17.0 mag.
MASTER II robotic telescope located in Blagoveschensk was pointed to the
GRB140108A 30 sec after notice time and 47 sec after trigger time at
2014-01-08 17:19:29.211 UT in two polarizations. On our first (10s
exposure) set we haven`t found optical transient within SWIFT error-box.
The 5-sigma upper limit has been about 16.0 mag.
The polarizations filters oriented by RA and DEC axis (0 and 90 degrees
from RA axis) in Kislovodsk, and 45 and 135 degrees from RA axis in
Blagoveschensk.
The OT candidate apeared in two sites (Blagoveschensk and Kislovodsk) and
at 2014-01-08 17:19:42 at position:
(J2000)
RA = 21 40 26.77
Dec = +58 44 41.4
Error=+-1 arcsc sigma
