TITLE: GCN GRB OBSERVATION REPORT NUMBER: 4712 SUBJECT: GRB 060206: More PROMPT Detections DATE: 06/02/08 07:05:32 GMT FROM: Aaron LaCluyze at U.North Carolina J. Kirshbrown, C. MacLeod, A. LaCluyze, J. Haislip, M. Nysewander, D. Reichart, J. A. Crain, A. Foster, and K. Ivarsen report on behalf of the UNC team of the FUN GRB collaboration: We continued to observe the localization of GRB 060206 (Morris et al., GCN 4682) with three of the PROMPT telescopes in Ui'I beginning 25.7 hours after the burst under the automated control of Skynet. We detect the afterglow (Fynbo et al., GCN 4683) at I = 18.79 +/- 0.16 mag at an effective time of 26.3 hours after the burst (calibrated to five SDSS stars; Cool et al., GCN 4695; using the transformation equations of Smith et al. 2002.) In the i' band, the afterglow continues to fade as a power law (Haislip et al., GCN 4709), with a best-fit temporal index of -1.05 between 1.63 and 26.3 hours after the burst. PROMPT is currently being built and commissioned at CTIO.
