TITLE: GCN CIRCULAR NUMBER: 38708 SUBJECT: GRB 241229B: Swift-XRT refined Analysis DATE: 24/12/29 14:06:47 GMT FROM: Phil Evans at U of Leicester pae9@star.le.ac.uk
P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team:
We have analysed 2.7 ks of XRT data for GRB 241229B, from 23.5 ks to 34.3 ks after the BAT trigger. The data are entirely in Photon Counting (PC) mode. The refined XRT position is RA, Dec = 274.1761, +74.6833 which is equivalent to:
RA (J2000): 18 16 42.26 Dec(J2000): +74 40 60.0
with an uncertainty of 6.8 arcsec (radius, 90% confidence). The source has a mean count rate of 1.4e-02 ct/sec; we cannot determine at the present time whether it is fading.
The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/01277428.
