RA(J2000) = 05h 17m 08s Dec(J2000) = +64d 11' 02"with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a double-peaked structure with a total duration of about 4 sec. The peak count rate was ~1000 counts/sec (15-350 keV), at ~0 sec after the trigger.
RA(J2000) = 05h 17m 13.75s Dec(J2000) = +64d 10' 26.2"with an uncertainty of 4.8 arcseconds (radius, 90% containment). This location is 49 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.

In addition, we note the presence of a galaxy just outside the current X-ray error circle (its centroid being 7.3+-3.6" away of the XRT position). It is visible also in the DSS images and has a magnitude R = 18.2 (assuming R = 17.54 for the star at RA=05:17:11.43, Dec=+64:10:10.88).
RA (J2000): 05h 17m 13.39s Dec (J2000): +64d 10' 24.6"with an uncertainty of 1.8 arcsec (radius, 90% confidence).
RA(J2000) = 05h 17m 10.8s Dec(J2000) = +64d 11' 56.4"with an uncertainty of 2.0 arcmin, (radius, sys+stat, 90% containment). The partial coding was 34%.
