RA(J2000) = 18h 59m 55s Dec(J2000) = -25d 15' 50"with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a peak with a with a duration of about 3 sec. There is a hint of a secondary peak around T+25 sec with a duration of 10 sec. The peak count rate was ~1400 counts/sec (15-350 keV), at ~1 sec after the trigger.
RA(J2000) = 18h 59m 53.51s Dec(J2000) = -25d 15' 39.8"with an uncertainty of 3.3 arcseconds (radius, 90% containment). This location is 28 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.
RA(J2000) = 18h 59m 55.5s Dec(J2000) = -25d 16' 42.0"with an uncertainty of 2.3 arcmin, (radius, sys+stat, 90% containment). The partial coding was 61%.
RA (J2000): 18h 59m 53.82s Dec (J2000): -25d 15' 39.6"with an uncertainty of 2.0 arcsec (radius, 90% confidence).
