GCN Circular 22606
C. Malacaria (NASA-MSFC/USRA) and A. von Kienlin (MPE) report on behalf of the Fermi GBM Team: "The Fermi Gamma-ray Burst Monitor (GBM) triggers 544628550/180405571 at 13:42:25.886 UT on 5 April 2018 544542853/180404579 at 13:54:08.080 UT on 4 April 2018 544531428/180404447 at 10:43:43.753 UT on 4 April 2018 tentatively classified as GRBs, are in fact not due to GRBs. These triggers are caused by an occultation step due to MAXI J1820+070 (von Kienlin, GCN Circ. 22595). Additional triggers are likely expected from this source in the next days which, however, will not be reported in future circulars."
