RA(J2000) = 17h 02m 17s Dec(J2000) = -35d 35' 55"with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a double-peaked structure with a duration of about 30 sec. The peak count rate was ~2500 counts/sec (15-350 keV), at ~0 and ~10 sec after the trigger.
RA(J2000) = 17h 02m 16.93s Dec(J2000) = -35d 35' 13.6"with an uncertainty of 4.1 arcseconds (radius, 90% containment). This location is 42 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.
