RA(J2000) = 19h 50m 45s Dec(J2000) = -32d 23' 16"with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). As is typical for image trigger GRBs, the BAT light curve shows little obvious variation. A detailed light curve will require the data downlinked via Malindi.
RA(J2000) = 19h 50m 48.8s Dec(J2000) = -32d 24' 18.7"with an uncertainty of 4.7 arcseconds (radius, 90% containment). This location is 79 arcseconds from the BAT on-board position, within the BAT error circle. The initial flux in the 2.5s image was 2.9e-09 erg/cm2/s (0.2-10 keV).
