TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1145 SUBJECT: XRF011030: J and K band observations DATE: 01/11/21 14:25:54 GMT FROM: Elena Pian at ITESRE-CNR,Bologna F. Mannucci (CAISMI, CNR, Firenze), V. Calamai (INAF, Oss. Astrofisico di Arcetri), E. Palazzi, N. Masetti (ITeSRE, CNR, Bologna), E. Pian (INAF, Astr. Obs. Trieste), P. Saracco (INAF, Astr. Obs. Brera), A. Antonelli (INAF, Astr. Obs. Rome), on behalf of a larger collaboration, report: We imaged the field of XRF011030 (GCN 1118) with TIRGO equipped with the near-IR camera ARNICA and the J and K filters on Oct 30, 18:15 - 21:22 UT. The PSF FWHM was about 2.0". A standard star for flux calibration is available in the K band only; the J band image was calibrated instead by using an average zero point. No source is detected at the position of the radio transient reported by Taylor et al. (GCN 1136), nor in the Chandra error box of the X-ray source detected by Harrison et al. (GCN 1143) to 5-sigma limiting magnitudes of J=19.8 and K=18.0. This message may be cited.
