TITLE: GCN GRB OBSERVATION REPORT NUMBER: 4449 SUBJECT: GRB 060105: quick look analysis of the Suzaku/XIS afterglow observation DATE: 06/01/09 01:40:38 GMT FROM: Makoto Tashiro at Saitama U/Swift K. Mitsuda, R. Fujimoto, T. Inui, T. Murakami and the Suzaku GRB-ToO team reports: The Suzaku narrow field instruments: XIS and HXD started observation of GRB060105 from 12:10 UT on 2006-01-05 (Mitsuda et al. GCN 4432), at 5.4 hours after the Swift BAT detection (Ziaeepour et al. GCN 4429). Preliminary analysis shows a fading X-ray source at the reported XRT position (Godet et al. GCN4433). The intensity decreased to 1/3 of the initial at the end of observation, 12:00 UT on 2006-01-06. The averaged flux during the observation is approximately 7x10^-13 erg/s/cm2 (2-10 keV). Detail analysis is in progress.
