TITLE: GCN GRB OBSERVATION REPORT NUMBER: 4709 SUBJECT: GRB 060206: PROMPT Detections DATE: 06/02/07 22:45:49 GMT FROM: Josh Haislip at U.North Carolina J. Haislip, A. LaCluyze, C. MacLeod, M. Nysewander, D. Reichart, J. A. Crain, A. Foster, K. Ivarsen, and J. Kirshbrown report on behalf of the UNC team of the FUN GRB collaboration: We observed the localization of GRB 060206 (Morris et al., GCN 4682) with two of the PROMPT telescopes in Ur'i' between 1.63 and 3.36 hours after the burst under the automated control of Skynet. The afterglow (Fynbo et al., GCN 4683) faded from r' = 16.85 +/- 0.05 mag to r' = 17.83 +/- 0.12 mag over this period (calibrated to five SDSS stars; Cool et al., GCN 4695.) The best-fit temporal index is -1.0. PROMPT is currently being built and commissioned at CTIO.
