Phil Evans at U of Leicester <>
P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team:

Using  promptly downlinked XRT event data for GRB 151006A, we find an
enhanced XRT position of the afterglow: RA, Dec: 147.4260, 70.5027
which is equivalent to:
   RA (J2000)  = 09 49 42.25
   Dec (J2000) = +70 30 09.7
with an uncertainty of 2.3 arcseconds (radius, 90% confidence).
Analysis of the promptly available data is online at

Position enhancement is is described by Goad et al. (2007, A&A, 476,
1401) and Evans et al. (2009, MNRAS, 397, 1177).
