We observed the field of the Swift GRB 111016A (Mangano et al., GCN 12439)
with 40-cm telescope ORI-40 of Kitab ISON observatory on Oct. 16 starting on
(UT) 22:07:26. On the stacked image we do not detect any source within the
enhanced XRT error box (Evans et al., GCN 12441). The photometry is based
on the reference star SDSS 101516.54+272642.0 assuming (after recalibration
gri->R) R=17.77:
