report on behalf of the Swift-XRT team:
Swift-XRT has performed follow-up observations of the Fermi/LAT-detected
burst GRB 161015A (Masanori Ohno et al., GCN 20054; Stanbro & Meegan,
GCN Circ. 20056) in a series of observations tiled on the sky. The total
exposure time is 5 ks, distributed over 4 tiles. The data were collected
between T0+38.2 ks and T0+45.8 ks, and are entirely in Photon Counting
(PC) mode.
An uncatalogued X-ray source is detected within the Fermi/LAT error circle.
The position of this source is RA, Dec=269.2518, +30.37356 which is
equivalent to:
RA (J2000): 17:57:00.43
Dec(J2000): +30:22:24.8
with an uncertainty of 2.7 arcsec (radius, 90% confidence). This
position is 12.2 arcmin from the Fermi/LAT position. The source has a
0.3-10 keV count rate of about 0.03 ct/sec. We cannot determine fading
at this time.
[GCN OPS NOTE(17oct16): Per author's request, the GRB name in the first sentence
was corrected from 16A to 15A.]
