GCN Circular 4719
Klotz, A. (CESR-OMP), Boer M. (OHP), Atteia J.L. (LATT-OMP) report: We imaged the field of GRB 060209 detected by SWIFT (trigger 180931) with the TAROT robotic telescope (D=25cm) located at the Calern observatory, France. First image was acquired 23.7s after the GCN trigger (10s after the notice). The field elevation decreased from 74 degrees above horizon and weather conditions were good (moon at 41.0deg, phase=0.79). All images are not filtered. Date of trigger : t0 = 2006 feb. 09 19:08:55.95 UTC First image is 30s exposure trailed. No OT is visible: t0+23.7s to t0+83.7s : R > 15.8 Second image is 30s exposure. No OT is visible: t0+90.2s to t0+120.2s : R > 17.2 We co-added a series of exposures. No OT is visible: t0+90.2s to t0+967.1s : R > 18.3 Galactic coordinates are lon=147.439131 lat=6.264359 and the galactic extinction in R band is 2.3 magnitudes from D. Schlegel et al. 1998ApJ...500..525S. Magnitudes were estimated with the nearby USNO-B1 This message may be cited.
