This monitor system looks\nfor excesses above the expected background in time windows of 0.2, 1, 10\nand 100 seconds.\nThis event was found in the 100-second time window starting\nat the reported trigger time.\n\nThe position of the alert is\nRA (J200): 92.54 deg\nDec (J2000): 5.50 deg\nLocation uncertainty (68% containment): 0.40 deg (statistical only).\n\nThe monitor system found that this alert has a false alarm rate of 4.35\nalert(s) per year.\nWe encourage follow-up observations of the HAWC alert region. We however\nnote that it is\nconsistent with background expectation based on the observation time.\n\nThe initial automated alert is recorded in here:\nhttps://gcn.gsfc.nasa.gov/notices_amon_hawc/10011037_4398.amon\n\nHAWC is a very-high-energy gamma-ray observatory operating in Central\nMexico at latitude 19 deg. north. Operating day and night with over\n95% duty cycle, HAWC has an instantaneous field of view of 2 sr and\nsurveys 2/3 of the sky every day. It is sensitive to gamma rays\nfrom 300 GeV to 100 TeV.",
