GCN Circular 4823
M. Capalbi, M. Perri, L. Vetere (ASDC), K.L. Page (U. Leicester), J. Kennea and D. Burrows (PSU) report on behalf of the Swift XRT team: We have analysed the Swift XRT data from the first seven orbits observation of GRB 060223 (Cummings et al. GCN 4813). We find an uncatalogued fading source at the following location: RA(J2000) = 03h 40m 49.74s Dec(J2000) = -17d 07' 48.0" We estimate an uncertainty of 3.7 arcseconds radius (90% containment). This position is 44 arcsec from the BAT position and 2.6 arcsec from the UVOT position given in GCN 4813. The large flare in the first orbit makes determination of an afterglow slope and extrapolation of the flux unreliable, and we will have to wait for further data before an afterglow slope can be established. A preliminary spectral fit to the Photon Counting mode data with an absorbed power law gives a photon index of 1.9 � 0.3 and NH consistent with the Galactic value (5.92E+20 cm^-2). This circular is an official product of the Swift XRT Team.
