Kennea (PSU), report:\n\nSwift/BAT did not localize GRB 220710A onboard (T0:\n2022-07-10T03:29:34 UTC, GECAM trig utn220710_032932_GECAMb).\n\nThe GECAM notice, distributed in near real-time, triggered the Swift\nMission Operations Center operated Gamma-ray Urgent Archiver for Novel\nOpportunities (GUANO; Tohuvavohu et al. 2020, ApJ, 900, 1).\n\nUpon trigger by this notice, GUANO sent a command to the Swift Burst\nAlert Telescope (BAT) to save 200 seconds of BAT event-mode data from\n[-50,+150] seconds around the time of the burst. All the requested\nevent mode data was delivered to the ground.\n\nThe burst is detected in BAT with a duration of ~25 seconds.\nThe burst occurred during a Swift slew.\nThe burst position is found with an image SNR of 20.\n\nThe BAT position is\nRA, Dec = 221.592, 20.657 deg which is\n   RA(J2000)  = 14h 46m 22.08s\n   Dec(J2000) =  20d 39��� 25.2���\nwith an uncertainty of 2 arcmin.\n\nXRT and UVOT follow-up has been requested\nResults of follow-up observations will be reported in future circulars.\n\nGUANO is a fully autonomous, extremely low latency, spacecraft\ncommanding pipeline designed for targeted recovery of BAT event mode\ndata around the times of compelling astrophysical events to enable\nmore sensitive GRB searches.",
