RA(J2000) = 09h 00m 17s Dec(J2000) = -47d 33' 53"with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a single peak structure with a duration of about 10 sec. The peak count rate was ~3407 counts/sec (15-350 keV), at ~0 sec after the trigger.
RA(J2000) = 09h 00m 05.78s Dec(J2000) = -47d 33' 37.9"with an uncertainty of 2.1 arcseconds (radius, 90% containment). This location is 110 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.
