D. Malesani (DARK/NBI), D. Xu (NAOC/CAS), H. Jonsson (Lund Univ.), and
P. Jakobsson (Univ. Iceland) report on behalf of a larger collaboration:
We observed the field of GRB 160607A (Ukwatta et al., GCN 19502) with
the Nordic Optical Telescope (NOT), located in La Palma (Canary
Islands). Observations were carried out at large airmass (~3) in the
SDSS i filter, for a total of 20 min on source, at a mean epoch 2016
June 8.19 UT (0.725 days after the BAT trigger).
Within the refined XRT position (Goad et al., GCN 19503), we detect a
single, faint source at coordinates (J2000):
RA = 00:54:40.14
Dec = -04:56:53.3
Carrying out photometry against the SDSS catalog, we derive a magnitude
i = 23.45 +- 0.20 AB. As this value is fainter than the SDSS limit, and
as we lack variability information, we cannot presently conclude whether
this source is the afterglow of GRB 160607A. Further observations are
planned, but will be probably delayed until the field has a better
visibility from La Palma.
