TITLE: GCN CIRCULAR NUMBER: 28734 SUBJECT: HAWC-201019A: not observable by Fermi-GBM DATE: 20/10/21 22:01:02 GMT FROM: Cori Fletcher at USRA C. Fletcher (USRA) reports on behalf of the Fermi-GBM Team: The HAWC Burst Monitor detected the burst signal HAWC-201019A (GCN 28709) with the reported position: RA: 203.148 deg (J2000) Dec: 29.717 (J2000) which was occulted by the Earth for Fermi-GBM from approximately 14.5 minutes prior until 14.8 minutes after event time. Therefore, the GBM observations are not constraining for prompt gamma-ray emission.
