TITLE: GCN CIRCULAR NUMBER: 7419 SUBJECT: SAX J1818.6-1703: Swift detection (trigger 306379) DATE: 08/03/15 16:12:54 GMT FROM: David Palmer at LANL S. D. Barthelmy (GSFC), H. A. Krimm (GSFC/USRA), C. B. Markwardt (CRESST/GSFC/UMD), D. M. Palmer (LANL) and T. N. Ukwatta (GSFC/GWU) report on behalf of the Swift Team: At 15:49:01 UT, the Swift Burst Alert Telescope (BAT) triggered and located trigger 306379. Swift did not slew and will not slew to this location. The BAT on-board calculated location is RA, Dec 274.679, -17.068 which is RA(J2000) = 18h 18m 43s Dec(J2000) = -17d 04' 04" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). This position is consistent with the known transient SAX J1818.6-1703. Therefore, it is not a gamma-ray burst.
