TO: All GCN Notice recipients RE: Fermi-LAT_Monitor and _Transient types are available DT: 26 Aug 2011 INTRODUCTION: The GCN system has been modified to incorporate the distribution of the Fermi-LAT "monitor" and "transient" notices. The Monitor notice reports flares from known sources that Fermi regularly monitors as part of its all-sky survey (168 sources, eg Blazars, AGN, etc). The Transient notice reports positions of non-GRB transient events detected by Fermi-LAT that are not associated with any previously known source. OCCURRANCE RATE: There will be about 25 Monitor flares per year. For Transient events, the occurance rate is less certain; it will be fewer than 10 per year. TIME DELAY: Both of these operations are automated ground-based analysis efforts and use search timescales of 1-day and 1-week timescales. As such, there is an intrinsic comparable delay (from the start of the transient) in reporting these events. LOCATION ERROR: The location uncertainties are in the 10-60 arcmin range (radius, 95% containment). ACTION ITEM: If, after reviewing the information below, you want to receive these Fermi-LAT_MONITOR or Fermi-LAT_TRANSIENT notices, please send me a request to have them enabled. You can do this by forwarding this email (which has your sitename identifier) to scott@milkyway.gsfc.nasa.gov . Or you can go to http://gcn.gsfc.nasa.gov/gcn/config_builder.html and select "#2 Modify an existing config". You can also take this opportunity to make other changes to your configuration. ARCHIVE STORAGE: The GCN/FERMI Notices are archived within the GCN website in the Table of FERMI Transients & Flares: http://gcn.gsfc.nasa.gov/gcn/fermi_lat_mon_trans.html This single archive page contains both types.
