RA(J2000) = 00h 41m 14s Dec(J2000) = +33d 58' 52"with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a single symmetric peak structure with a duration of about 1.5 sec. The peak count rate was ~4000 counts/sec (15-350 keV), at ~0.5 sec after the trigger.
RA(J2000) = 00h 41m 16.52s Dec(J2000) = +33d 59' 41.3"with an uncertainty of 3.7 arcseconds (radius, 90% containment). This location is 59 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.
