S. Maticic, B. Dintinjana and H. Mikuz on behalf of PIKA observing
program at Crni Vrh Observatory.
We observed the field of GRB 120116A (GCN 12834) from Crni Vrh
Observatory with a 60 cm robotic telescope, R filter and CCD. Twenty
consecutive exposures of 60 second duration were taken. First exposure
started at 2012-01-16 18:07:47 UT, 79 seconds after the burst (60
seconds after the SWIFT trigger).
No optical candidate was detected within the uncertainty radius on
single exposures, having R limiting magnitude 20.0 +/-0.2. Also we found
no optical candidate on 20 sumed R images with total exposure of 1200
seconds and limiting R band magnitude 22.0 +/-0.2 (all magnitudes
calibrated against the nearby USNO B1.0 R2 magnitude stars).
