TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1687 SUBJECT: GRB 021113: Optical Observations DATE: 02/11/13 15:36:37 GMT FROM: Melissa Nysewander at UNC,Chapel Hill M. Nysewander, D. Reichart (U. North Carolina), and M. Schwartz (Tenagra Observatories) report: We observed 100% of the 23 arcmin x 13 arcmin error box, but only 90% of the revised 26 arcmin x 9 arcmin error box, of GRB 021113 (GCN 1686) with the 32-inch Tenagra II telescope beginning 2.6 hours after the burst. We integrated without filter for 1800 seconds per pointing x two pointings. Visual comparison with the DSS2-Red reveals no obvious counterpart to the limiting magnitude of the DSS. Future observations are planned.
