Vetere (ASDC) report on behalf of the Swift Team: At 08:22:14 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 060510B (trigger=209352). Swift slewed immediately to the burst. The BAT on-board calculated location is RA,Dec 239.141, +78.559 {15h 56m 34s, +78d 33' 33"} (J2000) with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). Because this is an image trigger, the TDRSS BAT light curve does not show any significant activity around the trigger time, but we note that there is possible activity at T+150 and T+300 sec. This possible long duration could be an indication of a high redshift burst.

Barthelmy (GSFC), J. Cummings (GSFC/NRC), N. Gehrels (GSFC), S. Hunsberger (PSU), J. Kennea (PSU), H. Krimm (GSFC/USRA) on behalf of the Swift team: At 23:55:35 UT, Swift-BAT had an 80-sec image trigger. And because of an observing constraint, the spacecraft did not slew to the flight-derived location; and so there are no immediate XRT or UVOT data products to analyze. We note that the star tracker was not in lock at the time of the trigger. Past experience shows that the gyros are able to maintain sufficient tracking to prevent drift and therefore false triggers, but it is still possible that this current trigger is a false positive. We will get the full data set in about 2 hours and may be able to determine the validity of this trigger at that time.
