TITLE: GCN CIRCULAR NUMBER: 16468 SUBJECT: GRB 140622A: TAROT La Silla observatory optical observations DATE: 14/06/28 16:14:27 GMT FROM: Alain Klotz at IRAP-CNRS-OMP Klotz A., Turpin D. (IRAP-CNRS-OMP), Boer M., Gendre B., Siellez K., Dereli H., Bardho O. (UNS-CNRS-OCA), Atteia J.L. (IRAP-CNRS-OMP) report: We imaged the field of GRB 140622 detected by SWIFT (trigger 602278) with the TAROT robotic telescope (D=25cm) located at the European Southern Observatory, La Silla observatory, Chile. The observations started 23.2s after the GRB trigger (12.7s after the notice). The elevation of the field decreased from 61 degrees above horizon and weather conditions were excellents. Images were not accessible during one week due to a disk access problem. The first image is trailed with a duration of 60.0s (see the description in Klotz et al., 2006, A&A 451, L39). We do not detect any OT with a limiting magnitude of: t0+23.2s to t0+83.2s : R > 17.5 The second image is 30.0s exposure in tracking mode: t0+96.6s to t0+126.6s : R > 18.0 We co-added a series of exposures: t0+96.6s to t0+389.1s : R > 18.4 Magnitudes were estimated with the nearby USNO-B1 stars and are not corrected for galactic dust extinction.
