J. Wood (NASA/MSFC) reports on behalf of the Fermi-GBM Team: Swift-BAT detected GRB 220305A at 16:13:08 UT on 05 March, 2022 (Caputo et al. GCN 31684). There was no Fermi-GBM onboard trigger around the time of the event. An automated, blind search for short gamma-ray bursts below the onboard triggering threshold in Fermi-GBM identified no counterparts. The GBM targeted search , the most sensitive, coherent search for GRB-like signals identified a transient most significantly on the 8.192 s timescale, with a location consistent with the Swift-BAT event and a signal-to-noise ratio of 17.8, using the standard search protocol. The GBM targeted search event was found with the highest significance with a "normal" spectrum (Band function with Epeak = 230 keV, alpha = -1.0, beta = -2.3) for a GRB. This analysis is preliminary.  Goldstein et al. 2019 arXiv:1903.12597 Note: Fermi-GBM also detected GRB 220305B at 11:33:20.48 UT on 05 March 2022 which was erroneously named GRB 220305A at the time of its initial publication (GCN 31689, 31690). GRB 220305B is a different burst than the one described here.
