GRB 090519: FARO Chante Perdrix Observatory optical observations
?
SOURCE: GCN
TITLE: GCN CIRCULAR
NUMBER: 9402
SUBJECT: GRB 090519: FARO Chante Perdrix Observatory optical observations
DATE: 09/05/19 22:13:56 GMT
FROM: Alain Klotz at CESR-CNRS <Alain.Klotz@free.fr>

Klotz, A. (CESR-OMP), Kugel, F. (Obs. Chanteperdrix) report:

We imaged the field of GRB 090519 detected by SWIFT (trigger 352648) with the FARO robotic telescope (D=20cm) located at the Chante Perdrix Observatory, Banon, France. FARO stands for Francois & Alain Robotic Observatory: http://chanteperdrix.dyndns.org The observations started 122.4s after the GRB trigger (53.0s after the notice). The elevation of the field decreased from 22 degrees above horizon and weather conditions were good. The date of trigger : t0 = 2009-05-19T21:08:56.5 The first image is 60.0s exposure in tracking mode. We do not detect any OT at the XRT position mentionned by Perri et al. 2009 (GCN 9400) with a limiting magnitude of: t0+122.4s to t0+182.4s : R > 15.7 Magnitudes were estimated with the nearby USNO-B1 stars and are not corrected for galactic dust extinction. This message may be cited.
