GCN Circular 14098
S. D. Barthelmy (GSFC), N. Gehrels (NASA/GSFC), S. T. Holland (STScI) and C. J. Mountford (U Leicester) report on behalf of the Swift Team: At 22:44:35 UT, the Swift Burst Alert Telescope (BAT) triggered and located SGR 1E 1841-045 / Kes 73 (trigger=543763). Swift did not slew because of the Sun observing constraint. The BAT on-board calculated location is RA, Dec 280.334, -4.902, which is RA(J2000) = 18h 41m 20s Dec(J2000) = -04d 54' 08" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The real-time lightcurve packets were corrupted so nothing is known about the shape of the light curve, but presumably it is a single spike (typical of this source); and the trigger duration was 16 msec. The source will remain in Sun constraint until Feb 13. There will be no further observations by Swift.
