We observed the field of GRB 160303A detected by Swift (trigger #677495;
Beardmore et al., GCN Circ. 19126) with the iTelescope.Net (http://www.itelescope.net)
T21 (Plane Wave 17" CDK) telescope located at the New Mexico Skies Observatory
(NM, USA).
15 images of 60 sec exposures were taken in the R filter starting from March 3 11:19:26 (UT)
about 25 minutes after the trigger and stopped on March 3 11:38:20 (UT).
We do not detect the optical afterglow both in the individual images and the stacked image
at the X-ray and the optical afterglow position (Evans et al., GCN Circ. 19132;
Butler et al., GCN Circ. 19131). The estimated five sigma upper limit of the combined
image (total exposure of 900 sec) is ~18.3 using the USNO-B1 catalog.
