VOEvent alerts produced from transient detections resulting from observations with the NASA Fermi Gamma-ray Burst Monitor. Events should be reported within tens to hundreds of seconds; expect about one event a day, where most events correspond to either gamma ray burst, solar flares, or particles.There are streams giving alerts and localizations for gamma ray transients. Multiple localizations are produced for each event initially onboard the spacecraft (FERMI_GBM_FLT_POS), then improved via automated processing on the ground (FERMI_GBM_GND_POS), and the final position processed with improved analysis by more sophisticated software or the Burst Advocate (FERMI_GBM_FIN_POS). The FERMI_GBM SUBTHRESH stream has events produced from a ground pipeline processing of the data looking for transients that were below the on-board trigger threshold level and are typically used for coincidence searches with other data streams.
