There was no\nFermi-GBM onboard trigger around the event.\n\nAn automated, blind search for short gamma-ray bursts below the onboard\ntriggering threshold in Fermi-GBM identified no counterparts.\n\nThe GBM targeted search [1], the most sensitive, coherent search for\nGRB-like signals identified a transient most significantly on the 8.192 s\ntimescale, with a log likelihood ratio of 13 and a location consistent with\nthe MAXI/GSC event. The GBM targeted search event was found with the highest\nsignificance with a \"soft\" spectrum (Band function with Epeak=70 keV, alpha=-1.9,\nbeta=-3.7) for a GRB.\n\n\n[1] Goldstein et al. 2019 arXiv:1903.12597",
