RA(J2000) = 12h 24m 09s Dec(J2000) = +15d 04' 38"with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a double-peaked structure with a duration of about 30 sec. The peak count rate was ~1200 counts/sec (15-350 keV), at ~0 sec after the trigger.
RA(J2000) = 12h 24m 15.35s Dec(J2000) = +15d 06' 16.4"with an uncertainty of 2.2 arcseconds (radius, 90% containment). This location is 138 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.
RA (J2000): 12h 24m 15.48s Dec (J2000): +15d 06' 17.7"with an uncertainty of 1.8 arcsec (radius, 90% confidence).

RA(J2000) = 12:24:15.51 Dec(J2000) = +15:06:16.6with a positional uncertainty of 0.1" in each coordinate. The optical afterglow has a brightness of z = 20.27 +/- 0.11 AB mag, and is at least 3 mag fainter in our i-band observations. Both the astrometry and photometry are calibrated to SDSS.
Galactic foreground: 2.5 x 10^20 cm^-2 Intrinsic column: 1.7 (+3.2, -1.7) x 10^22 cm^-2 at z=6.32 Photon index: 1.75 (+0.12, -0.11)The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/00599037.
g' > 24.1 mag, r' > 24.5 mag, i' > 24.2 mag, z' = 22.1 +/- 0.1 mag, J = 20.9 +/- 0.2 mag, H = 20.9 +/- 0.2 mag, and K > 19.1 mag.Based on these data, the photometric redshift is z= 6.5 +/-0.2, which is consistent with the spectroscopic redshift reported by Chornock et al. (GCN 16269).
