TITLE: GCN CIRCULAR NUMBER: 13252 SUBJECT: GRB 120422A: NOT optical observations DATE: 12/04/23 01:25:22 GMT FROM: Dong Xu at Weizmann Inst S. Schulze (U. Iceland), D. Malesani (DARK/NBI), A. de Ugarte Postigo (IAA-CSIC, DARK/NBI), A. J. Levan (U Warwick), P. Jakobsson (U. Iceland), E. Wuyts (KIPAC Chicago) report on behalf of a larger collaboration: We observed the field of GRB 120422A (Troja et al., GCN 13243) with the Nordic Opitcal Telescope (NOT) equipped with MOSCA. We obtained 12 x 300 s I-band images. Observations started at 20:54 UT on April 22 (i.e., 13.3 hrs after the burst). We clearly detected the source reported in Cucchiara et al. (GCN 13245) in all individual images. There was no significant fading during observations. The source has an I-band brightness of 21.7 mag (Vega magnitude) in the stacked image. This value is not corrected for foreground extinction and calibrated with the #1039-0167772 star (I = 18.98 mag) in the USNO B1 catalogue.
