RA(J2000) = 03h 10m 28s Dec(J2000) = +13d 58' 28"with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a short spike with substructure with a duration of about 0.5 sec. The peak count rate was ~11000 counts/sec (15-350 keV), at ~0 sec after the trigger.
RA(J2000) = 03h 10m 21.74s Dec(J2000) = +13d 59' 43.7"with an uncertainty of 3.8 arcseconds (radius, 90% containment).

Magnitudes have not been corrected for line-of-sight Milky Way dust extinction, with expected E(B-V)=0.28 (Schlegel et al. 1998).
A summary of the PC-mode spectrum is thus: Total column: 1.29 (+0.67, -0.05) x 10^21 cm^-2 Galactic foreground: 1.2 x 10^21 cm^-2 Excess significance: <1.6 sigma Photon index: 1.49 (+0.20, -0.12)If the light curve continues to decay with a power-law decay index of 1.24, the count rate at T+24 hours will be 1.6 x 10^-3 count s^-1, corresponding to an observed (unabsorbed) 0.3-10 keV flux of 8.0 x 10^-14 (9.2 x 10^-14) erg cm^-2 s^-1.
r > 23.89 i > 23.79 Z > 22.86 Y > 22.38 J > 22.30 H > 21.78These magnitudes are in the AB system and are not corrected for Galactic extinction in the direction of the GRB. Our observations confirm that the source faded and is therefore the short GRB afterglow.
