E. Ambrosi (INAF-IASFPA), S. D. Barthelmy (GSFC), A. D'Ai (INAF-IASFPA), V. D'Elia (SSDC), A. Y. Lien (GSFC/UMBC) and K. L. Page (U Leicester) report on behalf of the Neil Gehrels Swift Observatory Team: At 06:34:00 UT, the Swift Burst Alert Telescope (BAT) triggered and located SGR 1935+2154 (trigger=933083). Swift did not slew to the source. The BAT on-board calculated location is RA, Dec 293.743, +21.896, which is RA(J2000) = 19h 34m 58s Dec(J2000) = +21d 53' 44" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows a single peak structure with a duration of about 0.2 sec. The peak count rate was ~4500 counts/sec (15-350 keV), at ~0 sec after the trigger. Swift did not slew to this source because the merit value of the source being observed by Swift was higher than the merit value for this known source.
