TITLE: GCN CIRCULAR NUMBER: 14242 SUBJECT: GRB 130216B: Swift/XRT observations DATE: 13/02/20 19:37:55 GMT FROM: Paolo D'Avanzo at INAF-OAB P. D'Avanzo, S. Campana, A. Melandri (INAF-OAB) report on behalf of the Swift team: We have analysed 1.9 ks of XRT data for GRB 130216B (Cummings GCN Circ. 14226; Chaplin GCN Circ. 14235), from 247.9 ks to 277.3 ks after the BAT trigger. The data are all in Photon Counting (PC) mode. No bright X-ray afterglow is detected inside the refined BAT error circle (Cummings et al. GCN Circ. 14232). The 3sigma upper limit is of 9.3 x 10^-3 cts/s. This corresponds to an observed 0.3-10 keV flux of 3.6 x 10^-13 erg/cm2/s (assuming a typical GRB spectrum with photon spectral index of 2). If we consider the Galactic absorption in this direction (1.3 x 10^21 cm^-2; Kalberla et al. 2005) this corresponds to an unabsorbed flux of 4.7 x 10^-13 erg/cm2/s. We note that there is a flux excess (SNR~2) at the edge (but inside) of the 1.5 arcmin radius BAT error circle, at the following position: RA, Dec=58.84993, +2.05183 which is equivalent to RA (J2000): 03h 55m 23.98s Dec (J2000): +02d 03' 06.6" with an uncertainty of 8.6 arcsec (radius, 90% confidence). The count rate at this position is (2.5 +/- 1.4) x 10^-3 cts/s.
