At 04:16:19 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 060424 (trigger=206773). Swift was not able to slew to the burst due to its proximity to the Sun. The BAT on-board calculated location is RA,Dec 7.355, +36.820 {00h 29m 25s, +36d 49′ 11″} (J2000) with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows a small spike on top of a weak peak starting about T-5 sec to about T+5 sec. The peak count rate was ~2000 counts/sec (15-350 keV), at ~0 sec after the trigger.

Because of the Sun observing constraint, there will not be any XRT or UVOT follow-up observations on this burst for at least 24 days.
