(DTU Space), K.E. Heintz (U.Iceland), S. Moran (UTU, NOT) report
on behalf of a larger collaboration:
We observed the field of GRB 190613B (D���Ai et al. GCN 24807,
Burgess et al. GCN 24808, Beardmore et al. GCN 24812, Bissaldi et
al. GCN 24814, Marshall et al. GCN 24817, Zheng & Filippenko
GCN 24818, Ukwatta et al. GCN 24820, Page et al. GCN 24823)
using STANCAM, mounted on the 2.5m Nordic Optical Telescope, at
Roque de los Muchachos Observatory (La Palma, Spain). The
observations consisted of 3x300s imaging in R-band and 5x200s in
z-band. Observations started on 14 June at 2:50 UT (16.05 hr after
the burst). The optical counterpart is well detected in both bands at
an estimated R(Vega) = 21.8+/-0.2 mag, as compared to field stars
from the Nomad catalogue.
