TITLE: GCN CIRCULAR NUMBER: 22975 SUBJECT: Correction: Swift trigger #848890 is GRB 180720B (not GRB 180720A) DATE: 18/07/20 14:48:26 GMT FROM: Amy Lien at GSFC M. H. Siegel (PSU), D. N. Burrows (PSU), A. Deich (PSU), J.D. Gropp (PSU), J. A. Kennea (PSU), S. J. LaPorte (PSU), A. Y. Lien (GSFC/UMBC), M. J. Moss (George Washington University), K. L. Page (U Leicester), D. M. Palmer (LANL), B. Sbarufatti (PSU) and A. Tohuvavohu (PSU) report on behalf of the Neil Gehrels Swift Observatory Team: The GRB name in GCN Circ. #22973 should be GRB 180720B because of an earlier detection of GRB 180720A from AGILE/MCAL (GCN Circ. #22970). We apologize for the mistake and any confusion caused by this.
