D. Malesani (DARK/NBI), D. Xu (DARK/NBI), H. Dahle (Univ. Oslo), E. Soto
(CUA), report on behalf of the Nordic GRB collaboration:
We observed the field of GRB 140428A (Kocevski et al., GCN 16177) with
the NOT equipped with the ALFOSC imager. Observations started on 2014
Apr 29.223 UT (5.34 hr after the GRB) and consisted of 20 minutes in r
and 12 in z.
Within the X-ray error circle (Page et al., GCN 16178), we do not find
any object down to a depth r > 22.5 and z > 20.5 (all AB), calibrated to
the SDSS.
DM thanks Thomas Kruehler (ESO) for insightful discussion.
