S. Schulze (PUC and MCSS), T. Kruehler (ESO Chile), N. R. Tanvir (U Leicester), A. A. Djupvik (NOT), and P. Jakobsson (U Iceland) report on behalf of a larger collaboration:
We observed the field of GRB 140318A (Cenko et al., GCN 15986) with 2.5m the Nordic Optical Telescope (NOT) equipped with StanCAM. We obtained 3 x 300 s in the R band. Observations started at 00:52:00 UT on March 18 (i.e. 43 min after the burst).
We detect a bright point source at the position
R.A.(J2000) = 12:16:21.40
Dec. (J2000) = +20:12:31.9
We measure R = 19.7 +/- 0.1 mag at 45 min after the trigger. The object coincides with a faint galaxy in the SDSS catalog which we identify as the putative host galaxy. SDSS J121621.38+201232.1 has a r'-band magnitude of 22.87 +/-0.26 mag(AB) and a photometric redshift of 0.42 +/- 0.02.
