At 22:30:26.42 UT, the Swift-BAT instrument triggered (trigger=146129) on GRB 050715. The spacecraft did not slew to this new burst because of the Sun observing constraint (and it will remain in constraint for 2-3 months). The BAT flight-determined location is RA,Dec 155.669,-0.059 {+10h 22m 41s, -00d 03′ 31″} (J2000) with a 3 armin uncertainty (radius, 90% containment, stat+sys). The lightcurve has two main peaks separated by ~35 sec with a total duration of ~70 sec. There is some evidence of 1 or 2 more smaller peaks. The peak count rate is ~1400 cnts/sec in the 15-350 keV band.
