RA(J2000) = 02h 36m 39s Dec(J2000) = +18d 09' 04"with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows a single spike with a duration of about 0.1 sec. The peak count rate was ~3200 counts/sec (15-350 keV), at ~0 sec after the trigger.
RA(J2000) = 02h 36m 29.90s Dec(J2000) = +18d 08' 45.7"with an uncertainty of 3.5 arcseconds (radius, 90% containment). This location is 125 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.
