RA(J2000) = 05h 47m 24.99s Dec(J2000) = -65d 30' 12.9"with an uncertainty of 3.5 arcseconds (radius, 90% containment). This location is 128 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 https://www.swift.ac.uk/sper.
