TITLE: GCN CIRCULAR NUMBER: 14372 SUBJECT: GRB 130408A: Zadko observatory - Gingin optical observations DATE: 13/04/09 19:16:12 GMT FROM: Husne Dereli at ARTEMIS/OCA H. Dereli (UNS-CNRS-OCA), A. Klotz (IRAP-CNRS-OMP), D. Macpherson (UWA/ICRAR), D. Coward (UWA), B. Gendre (IRAP-CNRS-OMP), M. Boer, K. Siellez, O. Bardho (UNS-CNRS-OCA), A. Williams (PO-UWA), R. Martin (PO-UWA) We imaged the field of GRB 130408A detected by SWIFT (trigger 553132) with the Zadko robotic telescope (D=100cm) located at the observatory - Gingin, Australia. The observations started 13.99h after the GRB trigger. The elevation of the field increased from 87.5 degrees above horizon and weather conditions were good. The co addition of the six images filtered C, g, r gives one image with an equivalent exposure time of 540s. We did not detected the afteglow mentioned in Melandri et al. (GCNC 14362): t0+13.99h to t0+14.56h : Rlim = 20.5 The limiting magnitude of the zadko image is R~20.5. Magnitudes were estimated with the nearby NOMAD1 stars and are not corrected for galactic dust extinction. [GNC OPS NOTE(17apr13): Per athor's request, the GRB name was changed from "1130408A" to "130408A".]
