RA(J2000) = 16h 47m 16s Dec(J2000) = +27d 14' 12"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 40 sec. The peak count rate was ~3000 counts/sec (15-350 keV), at ~10 sec after the trigger.
RA(J2000) = 16h 47m 19.60s Dec(J2000) = +27d 16' 50.9"with an uncertainty of 2.2 arcseconds (radius, 90% containment). This location is 163 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.
