Parsotan (GSFC/UMBC/CRESSTII) report on\nbehalf of the Neil Gehrels Swift Observatory Team:\n\nAt 16:13:08 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 220305A (trigger=1095215).  Due to a viewing constraint,\nSwift did not immediately slew.  The BAT on-board calculated location is \nRA, Dec 107.584, -37.708 which is \n   RA(J2000) = 07h 10m 20s\n   Dec(J2000) = -37d 42' 29\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed a complex\nstructure with a duration of about 40 sec.  The peak count rate\nwas ~1500 counts/sec (15-350 keV), at ~0 sec after the trigger. \n\nDue to an observing constraint, Swift will not slew until T0+46.5\nminutes. There will be no XRT or UVOT data until this time. \n\nBurst Advocate for this burst is R. Caputo (regina.caputo AT nasa.gov). \nPlease contact the BA by email if you require additional information\nregarding Swift followup of this burst. In extremely urgent cases, after\ntrying the Burst Advocate, you can contact the Swift PI by phone (see\nSwift TOO web site for information: http://www.swift.psu.edu/)",
