RA(J2000) = 10h 55m 09s Dec(J2000) = +22d 26' 58"with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a multi-peaked structure with a duration of about 60 sec. The peak count rate was ~17000 counts/sec (15-350 keV), at ~0 sec after the trigger.
RA(J2000) = 10h 55m 09.87s Dec(J2000) = +22d 27' 30.3"with an uncertainty of 2.5 arcseconds (radius, 90% containment). This location is 33 arcseconds from the BAT onboard position, within the BAT error circle. This position may be improved as more data are received; the latest position is available at http://www.swift.ac.uk/sper. We cannot determine whether the source is fading at the present time.

COMMENTS: This Notice was ground-generated -- not flight-generated. COMMENTS: This is an Update Notice -- the RA,Dec values herein supersede the previous XRT_POS Notice. COMMENTS: TAM values, flux and significance fields are not valid. COMMENTS: This position was automatically generated on the ground using COMMENTS: Photon Counting data telemetered via TDRSS (SPER data). COMMENTS: See http://www.swift.ac.uk/sper/docs.php for details. COMMENTS: This position was enhanced using UVOT field astrometry.
