TITLE: GCN CIRCULAR NUMBER: 16352 SUBJECT: Swift Trigger 600914 is probably a noise fluctuation DATE: 14/06/05 23:23:03 GMT FROM: Scott Barthelmy at NASA/GSFC S. D. Barthelmy (GSFC), J. A. Kennea (PSU), D. M. Palmer (LANL), M. C. Stroh (PSU) and C. A. Swenson (PSU) report on behalf of the Swift Team: At 23:06:51 UT, the Swift Burst Alert Telescope (BAT) triggered on probably noise in the image domain near the on-board catalog source NGC0746 (trigger=600914). Swift did not slew because of the Sun observing constraint. The BAT on-board calculated location is RA, Dec 29.393, +44.977, which is RA(J2000) = 01h 57m 34s Dec(J2000) = +44d 58' 36" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT real-time light curve does not show anything significant as is typical for image trigger. We will know more when the full data set is downlinked and analyzed.
