larger GRB follow up collaboration report:
We observed the field of the Swift GRB 120106A (Beardmore et al., GCN
12810) with ORI-40 telescope of Kitab ISON observatory on Jan. 6 starting on
(UT) 18:49:24. We obtained several unfiltered images between (UT) 18:49:24 -
19:20:20. On the stacked image we do not detect any source within the
enhanced XRT error box (Evans et al., GCN 12813). The photometry is based
on nearby reference stars of USNO-B1.0 (R2 magnitudes):
