report on behalf of the MASTER Team:
MASTER-Amur robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in Blagoveschensk was pointed to the GRB160104A (Melandri et
al., GCN 18815) 10 sec after notice time and 32 sec after trigger time
at 2016-01-04 11:24:46 UT. On our first (10s exposure) set we have
found optical transient with 17.0+/-0.3 unfiltered magnitude at LCOGT-FTN
and
MITSuME Akeno position (Guidorzi et al., GCN 18816; Saito et al., GCN 18817)
The 5-sigma upper limit has been about 17.3 mag
MASTER-Tunka robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located near Bykal lake was pointed to the GRB160104A 66 sec after
trigger time at 2016-01-04 11:25:20 UT. On our first (10s exposure) set
we have found marginally optical transient ~17 unfiltered magnitude.
The 5-sigma upper limit has been about 17.2mag
The reduction is continuated.
