TITLE: GCN CIRCULAR NUMBER: 28248 SUBJECT: Alert from the HAWC Burst Monitor HAWC-200814A DATE: 20/08/14 22:32:25 GMT FROM: Hugo Ayala at Pennsylvania State University The HAWC Collaboration (http://www.hawc-observatory.org/collaboration/) reports: On 2020/08/14, at 21:38:01 UTC, HAWC detected a burst signal from its Burst Monitoring named HAWC-200814A. This monitor system looks for excesses above the expected background in time windows of 0.2, 1, 10, and 100 seconds. This event was found in the 0.2-second time window starting at the reported trigger time. The position of the alert is RA (J200): 177.79 deg Dec (J2000): 19.94 deg Location uncertainty (68% containment): 0.8 deg (statistical only). The monitor system found that this alert has a false alarm rate of 0.37 per year. We encourage follow-up observations of the HAWC alert region. We, however, note that it is consistent with background expectations based on the observation time. The initial automated alert is recorded here: https://gcn.gsfc.nasa.gov/gcn/notices_amon_hawc/9575_1797.amon HAWC is a very-high-energy gamma-ray observatory operating in Central Mexico at latitude 19 deg. north. Operating day and night with over 95% duty cycle, HAWC has an instantaneous field of view of 2 sr and surveys 2/3 of the sky every day. It is sensitive to gamma rays from 300 GeV to 100 TeV.
