TITLE: GCN CIRCULAR NUMBER: 19699 SUBJECT: GRB 160714A: Optical observations from OSN DATE: 16/07/14 03:49:13 GMT FROM: Antonio de Ugarte Postigo at IAA-CSIC A. de Ugarte Postigo (IAA-CSIC, DARK/NBI), A. Sota (IAA-CSIC) report on behalf of a larger collaboration: We have observed the field of GRB 160714A (Siegel et al. GCN 19697) with the 1.5m OSN telescope, in Granada (Spain). Observations started at 2:33 UT (14 min after the GRB onset) and consisted of 3x180s + 4x300s I-band images. Each of the individual images cover the complete BAT error circle. In a preliminary analysis we detect no new source within the BAT error box down to a 3-sigma limit of I(AB) > 20.5 mag in the first image, and down to I(AB) > 21.5 mag in the combined image (mean time 2:48 UT, 29 minutes after the burst), as compared to SDSS data.
