RA(J2000) = 02h 44m 38s Dec(J2000) = -43d 28' 49"with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a single-peaked structure with a duration of about 5 sec. The peak count rate was ~1800 counts/sec (15-350 keV), at ~0 sec after the trigger.

g' > 26.5 mag, r' > 26.5 mag, i' > 25.6 mag, z' > 25.0 mag, J > 22.7 mag, H > 22.2 mag, and K > 21.3 mag.The given limits are derived based on calibrating the images against GROND zero points and 2MASS field stars and are not corrected for the Galactic foreground extinction corresponding to a reddening of E_(B-V)= 0.02 in the direction of the burst (Schlegel et al. 1998).
