TO: All GCN Notice recipients RE: SNEWS Notice type is available DT: 17 Dec 2015 INTRODUCTION: The GCN system has been modified to incorporate the distribution of the SNEWS notices (SuperNova Early Warning System). The SNEWS notice reports significant detections of bursts of neutrinos from single detectors and neutrino coincidences from 2-or-more detectors in the SNEWS network. OCCURRENCE RATE: There will be about 0.03 or fewer SNEWS Individual-detection Notices per year, and about 0.03 or fewer SNEWS Coincident-detection Notices per year. TIME DELAY: The operations at each of the 7 SNEWS detectors and the SNEWS central computer is automated resulting in a time delay minuets to hours (from when the neutrinos pass through the respective detectors to when the Notice is available to the public). LOCATION ERROR: The location uncertainties, if location information is available, are in the ~5-10 deg range (radius, 68% containment). TEST NOTICES: There is a test version which gets issued by the SNEWS Team every 7 days (12:00 US_Eastern timezone every Tuesday). ACTION ITEM: If, after reviewing the information below, you want to receive these SNEWS notices, please send me a request to have them enabled. You can do this by forwarding this email (which has your sitename identifier) to sbarthel@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 (appended below). ARCHIVE STORAGE: The GCN/SNEWS Notices are archived within the GCN website in the table of SNEWS Notices: http://gcn.gsfc.nasa.gov/gcn/snews_trans.html This single archive page contains both types. MORE INFORMATION: Can be found at: http://gcn.gsfc.nasa.gov/gcn/snews.html NOTICE EXAMPLE: Here are examples of a full-format email SNEWS REAL & TEST / COINCIDENT & INDIVIDUAL Notices: (Note: Even the one labeled "REAL" is constructed from bogus but typical data; and the EXPT names have been replaced with generic names. The real names are: Super-K, LVD, IceCube, KamLAND, Borexino, Daya_Bay, and HALO.) ///////////////////////// SNEWS e-mail format ////////////////////////////// TITLE: GCN/SNEWS EVENT NOTICE NOTICE_DATE: Sun 17 Nov 13 18:14:02 UT NOTICE_TYPE: REAL COINCIDENCE TRIGGER_NUM: 1000001 EVENT_RA: 3.00d {+00h 12m 00s} (J2000), 3.18d {+00h 12m 43s} (current), 2.36d {+00h 09m 26s} (1950) EVENT_DEC: +6.00d {+06d 00' 00"} (J2000), +6.08d {+06d 04' 37"} (current), +5.72d {+05d 43' 19"} (1950) EVENT_ERROR: 10.0 [deg radius, statistical plus systematic] EVENT_FLUENCE: 10 [neutrinos] EVENT_TIME: 68400.00 SOD {19:00:00.00} UT EVENT_DATE: 16593 TJD; 301 DOY; 13/10/28 EVENT_DUR: 10.00 [sec] EXPT: Expt_A Good, Expt_B Good, Expt_C Good, Expt_D Good, Expt_E Good, Expt_F Good SUN_POSTN: 233.23d {+15h 32m 54s} -19.15d {-19d 08' 55"} SUN_DIST: 129.64 [deg] Sun_angle= -8.7 [hr] (East of Sun) MOON_POSTN: 55.07d {+03h 40m 16s} +17.71d {+17d 42' 25"} MOON_DIST: 51.91 [deg] MOON_ILLUM: 100 [%] GAL_COORDS: 105.42,-55.53 [deg] galactic lon,lat of the event ECL_COORDS: 5.14, 4.31 [deg] ecliptic lon,lat of the event COMMENTS: SNEWS Event with RA,Dec coordinates.
