K.L. Page, P.A. Evans and M.R. Goad (U. Leicester) report on behalf of the
Swift-XRT team:
Using 3686 s of XRT Photon Counting mode data and 3 UVOT images, 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 =
192.11266, 8.69309 which is equivalent to:
RA (J2000): 12 48 27.04
Dec (J2000): +08 41 35.1
with an uncertainty of 2.0 arcsec (radius, 90% confidence).
This position may be improved as more data are received. Position
enhancement is described by Goad et al. (2007, A&A, 476, 1401) and Evans
et al. (2009, MNRAS, 397, 1177).
Please note that we still cannot confirm that this source is fading.
