GCN Circular 11049

M. C. Stroh and E. A. Hoversten (PSU) report on behalf of the Swift-XRT team:

Using promptly downlinked data we find a fading, uncatalogued X-ray source with an enhanced position: RA,Dec = 299.8760, 52.6279 (degrees) which is equivalent to:

RA  (J2000.0) = 19 59 30.23
DEC (J2000.0) = +52 37 40.3

with an uncertainty of 2.3 arcsec (radius, 90% containment). This location is 48.4 arcseconds from the BAT onboard position, inside the BAT error circle.

This position may be improved as more data are received. The latest position can be viewed at http://www.swift.ac.uk/xrt_positions. Position enhancement is described by Goad et al. (2007, A&A, 476, 1401) and Evans et al. (2009, MNRAS, 397, 1177).
