Information on resource 'GCN VOEvent Streams From Fermi-LAT'
description: VOEvent alerts produced from transient detections
resulting from observations with the NASA Fermi Large Area Telescope.
Events should be reported within tens to of seconds to days; expect
about one event a month, where most events correspond to either gamma
ray burst, or a known flaring source typically an active galactic
nuclei.
Streams giving alerts and localizations for gamma ray
transients. Rare onboard LAT detections of gamma-ray bursts are
distributed (FERMI_LAT_POS_INI) and updated (FERMI_LAT_POS_UPD) within
seconds, but more typically detected in ground processing and analysis
by Burst Advocates (FERMI_LAT_OFFLINE). Known sources that go into
outburst are distributed within a day (FERMI_LAT_MONITOR).
