Probable SGR 1833-0832: Enhanced Swift-XRT position
2010-03-20T07:42:38Z (14 years ago)
Phil Evans at U of Leicester <>
P.A. Evans and M.R. Goad (U. Leicester) report on behalf of the Swift-XRT team:

Using 5452 s of XRT Photon Counting mode data and 8 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 = 278.43520, -8.51880 which is equivalent to:

RA (J2000):  18 33 44.45
Dec (J2000): -08 31 07.7

with an uncertainty of 1.6 arcsec (radius, 90% confidence).

This position may be improved as more data are received.  The latest position
can be viewed at; all XRT products for this
event are available at Position
enhancement is described by Goad et al. (2007, A&A, 476, 1401) and Evans et al.
(2009, MNRAS, 397, 1177).
