TITLE: GCN CIRCULAR NUMBER: 13067 SUBJECT: GRB 120302A: Swift XRT refined analysis DATE: 12/03/16 12:08:34 GMT FROM: Vanessa Mangano at INAF-IASFPA V. Mangano, A. Maselli (INAF-IASFPA), and T. Sakamoto (GSFC/UMBC) report on behalf of the Swift-XRT team: Swift performed two additional ToO observations of the field of GRB 120302A on 2012 March 8 (4.3 ks starting at 05:39:10 UT) and on 2012 March 13 (7.4 ks starting at 06:10:37 UT). In both observations the previously detected XRT source (Sakamoto, et al., GCN Circ. 13012) is still visible and is detected with marginal significance of about 2.5 sigma. The 0.3-10 keV XRT lightcurve shows a decay trend, and a fit with a power-law model gives a decay slope of 0.76 +/- 0.13. The source is a possible X-ray afterglow candidate for GRB 120302A. This circular is an official product of the Swift-XRT team.
