The XRT paragraph in the GCN 6594 contains a error. We stated
that the XRT position was "outside" the BAT error circle -- it is,
in fact, inside. The corrected XRT paragraph is:
The XRT began observing the field at 20:08:30 UT, 153 seconds after the
BAT trigger. The on-board XRT position was not correct, because the
algorithm centroided on a hot pixel. From the ground data analysis,
a moderately bright and uncatalogued X-ray source was found
at RA, Dec 354.69922, + 66.25226 which is
RA(J2000) = 23h 38m 47.8s
Dec(J2000) = 66d 15' 08.1"
with an uncertainty of 5.5 arcseconds (radius, 90% containment).
This location is 40.8 arcseconds from the BAT on-board position
and within the BAT error circle. The initial flux in the 2.5s
image was 3.7e-10 erg/cm2/s (0.2-10 keV).
We apologize for the mistake. We would like to thank Alex Kann
for pointing the error.
