TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5448 SUBJECT: GRB 060814: TAROT optical observations DATE: 06/08/15 00:05:15 GMT FROM: Alain Klotz at CESR-CNRS Klotz, A. (CESR-OMP), Boer M. (OHP), Atteia J.L. (LATT-OMP) report: We imaged the field of GRB 060814 detected by SWIFT (trigger 224552) with the TAROT robotic telescope (D=25cm) located at the Calern observatory, France. First image was acquired 21.5s after the GRB trigger (6s after the notice). 3 first images were recorded during the gamma propt emission. The field elevation decreased from 11 degrees above horizon and weather conditions were good. Date of trigger : t0 = 2006-08-14T23:02:18.816 First image is 60s exposure trailed. No OT is visible: t0+21.5s to t0+81.5s : R > 14.8 Second image is 30s exposure. No OT is visible: t0+88s to t0+118s : R > 15.7 Third image is 30s exposure. No OT is visible: t0+125s to t0+155s : R > 15.7 Fourth image is 30s exposure. No OT is visible: t0+161s to t0+191s : R > 15.7 We co-added a series of exposures. No OT is visible: t0+88s to t0+228s : R > 17.4 Magnitudes were estimated with the nearby USNO-B1 stars Galactic coordinates are lon= 24.9891 lat=+63.2011 and the galactic extinction in R band is 0.1 magnitudes estimated from D.
