B. Dintinjana and H. Mikuz on behalf of PIKA observing program at Crni
Vrh Observatory.
We observed the field of GRB 100302A (Cummings et al., GCN 10458) from
Crni Vrh Observatory with a 60 cm robotic telescope, R filter and CCD.
Twenty consecutive exposures of 60 second duration were taken in
moonlight conditions. First exposure started at 2010-03-02 19:56:20 UT,
194 seconds after the burst (105 seconds after the SWIFT trigger).
No optical candidate was detected within the uncertainty radius on
single exposures, having R limiting magnitude 18.3, calibrated against
the nerby USNO-B R2 magnitude stars. Also we found no optical candidate
on 20 sumed R images with total exposure of 1200 seconds and limiting R
band magnitude 19.6 (calibrated against the nerby USNO-B R2 magnitude
stars).
