RA(J2000) = 02h 44m 21s Dec(J2000) = +35d 29' 36"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 ~3000 counts/sec (15-350 keV), at ~0 sec after the trigger.
RA(J2000) = 02h 44m 16.27s Dec(J2000) = +35d 29' 57.9"with an uncertainty of 2.2 arcseconds (radius, 90% containment). This location is 60 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. We cannot determine whether the source is fading at the present time.
RA (J2000.0) = 02 h 44 m 16.30 s DEC (J2000.0) = +35d 29' 08.4with an uncertainty of 0.5" in each coordinate.
RA (J2000.0) = 02 h 44 m 16.30 s DEC (J2000.0) = +35d 29' 57.1Sorry for any confusion caused by this mistake.
r' = 19.90 at dt = 3.6 min i' = 19.80 at dt = 5.0 minOver the course of the first hour following the Swift trigger time, the source fades by >~ 1.0 mag in r', confirming that it is indeed the optical afterglow of GRB140710A.
