We observed the afterglow of GRB 190114C (Gropp et al., GCN 23688) with
the 2-m Himalayan Chandra Telescope (HCT) located at the Indian
Astronomical Observatory, Hanle, India. The observations started on
2019-01-15 (14:51:32 UT) and two Bessell R-band images were obtained in
a gap of about 1.3 hr. The exposure time was 200 sec for each frame. The
OT candidate (Lipunov et al., GCN 23693; Selsing et al., GCN 23695;
Bolmer et GCN 23702; D'Avanzo et al., GCN 23729; Kim et al., GCN 23732,
23734; Kumar et al., GCN 23733) is clearly detected in our frames with
the following magnitudes:
UT-mid JD Mag
------------------- ---------- --------------
2019-01-15 14:53:13 2458499.12 19.70 +/- 0.10
2019-01-15 16:13:33 2458499.18 19.81 +/- 0.09
These magnitudes were calibrated using the magnitudes of field stars
from the USNO-B1.0 catalogue.
We thank the observing staff at IAO and CREST for helping with the
observations.
