GCN Circular 17958
S. D. Barthelmy (GSFC), L. M. Z. Hagen (PSU) and B. Sbarufatti (INAF-OAB/PSU) report on behalf of the Swift Team: At 22:42:08 UT, the Swift Burst Alert Telescope (BAT) triggered and located H1745-203 (trigger=645944). Swift did not slew due a higher merit value source being observed. The BAT on-board calculated location is RA, Dec 267.232, -20.395, which is RA(J2000) = 17h 48m 56s Dec(J2000) = -20d 23' 42" with an uncertainty of 4 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows a single peak with a duration of about 10 sec. The peak count rate was ~1000 counts/sec (15-350 keV), at ~1 sec after the trigger.
