TITLE: GCN CIRCULAR NUMBER: 19030 SUBJECT: GRB 160220A: TAROT Calern and TAROT La Silla observatory optical observations DATE: 16/02/20 13:43:43 GMT FROM: Alain Klotz at IRAP-CNRS-OMP Klotz A., Turpin D., Atteia J.L. (CNRS-OMP-IRAP), Boer, M., Laugier, R. (CNRS-ARTEMIS), Gendre B. (UVI - Etelman Obs.) report: We imaged the field of GRB 160220A detected by SWIFT (trigger 674670) with the TAROT robotic telescopes (D=25cm) located at the Calern observatory, France and at the European Southern Observatory, La Silla observatory, Chile. The observations started 1.64h after the GRB trigger at Calern and 4.00h after the GRB trigger at la Silla (the field was not visible at the date of the trigger). The elevation of the field increased from 20 degrees above horizon and weather conditions were good. We co-added a series of exposures. We do not detected the X-ray couterpart mentioned by Campana et al.
