FROM:    Phil Evans at U of Leicester  <pae9@leicester.ac.uk>

P.A. Evans (U. Leicester) and A. Amral-Rogers (U. Leicester) report on
behalf of the Swift-XRT team:

Using 1.7 ks of XRT Photon Counting mode data and 5 UVOT images for GRB
131014A, we find an astrometrically corrected X-ray position (using the 
XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 
catalogue): RA, Dec = 100.30220, -19.09781 which is equivalent to:
   RA (J2000.0)	= 06h 41m 12.53s
   Dec (J2000.0) = -19d 05' 52.1"
with an uncertainty of 2.3 arcsec (radius, 90% confidence).

This position is 5.9 arcsec from the initial XRT position reported by 
Kennea & Rogers (GCN 15335) and 11.2 arcmin from the LAT position 
(Desiante et al. (GCN 15333), but 4.1 arcsec from the NOT optical 
position of Schulze et al (GCN 15337).
