Trigger 1249653: Swift detection of SGR 1E 1841-045 / Kes 73
Abstract
At 19:01:18 UT, the Swift Burst Alert Telescope (BAT) triggered on SGR 1E 1841-045 / Kes 73 (trigger=1249653). Swift did not slew to the source. The BAT on-board calculated location is RA, Dec 280.339, -4.928 which is RA(J2000) = 18h 41m 21s Dec(J2000) = -04d 55' 39" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a double-peaked structure with a duration of about 0.5 sec. The peak count rate was ~30000 counts/sec (15-350 keV), at ~0 sec after the trigger. NO XRT or UVOT data is available since the spacecraft did not slew to the source.
