P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team:
Using promptly downlinked XRT event data for GRB 151215A, we find an
enhanced XRT position of the afterglow: RA, Dec: 93.5840, 35.5162 which
is equivalent to:
RA (J2000) = 06 14 20.17
Dec (J2000) = +35 30 58.3
with an uncertainty of 2.2 arcseconds (radius, 90% confidence).
Analysis of the promptly available data is online at
http://www.swift.ac.uk/sper/667392.
Position enhancement is is described by Goad et al. (2007, A&A, 476,
1401) and Evans et al. (2009, MNRAS, 397, 1177).
This circular is an official product of the Swift-XRT team.
