  "body": "During the past two weeks, the final testing of HETE-GCN rapid data \ninterfaces was successfully completed.  Beginning today, HETE \nlocalization releases are fully automatic.  HETE Notices will now be \npromptly distributed through the GCN system.  The HETE positions\nare calculated on-board, down-linked through the 12 Secondary ground\nstations, forwarded to the HETE Ops computer at MIT, and then forwarded\nto GCN for distribution to those GCN sites that have elected to receive\nthe GCN/HETE Notices (Alert, Update, Final, and/or GroundAnalysis subtypes).\nThis is the full automated process; there are no humans in the loop,\ni.e. the minimum possible delay time.  The time delays range\nfrom 10 sec to 30 sec for the Alert and Update Notices (Updates are\nthe first notice subtype that has position information.)\n\nA detailed description of the HETE Notices is contained in:\nhttp://gcn.gsfc.nasa.gov/gcn/hete.html\nand for the socket sites, the packets are defined in:\nhttp://gcn.gsfc.nasa.gov/gcn/sock_pkt_def_doc.html\n\nIt should be stressed that because this is the fully automated, \n\"hands off\" processing procedure, there will inevitably be non-GRB \ntriggers included in those sent to the ground and distributed.\nIn fact, during the June-July period, when the Galactic Bulge region\nis passing through the HETE field-of-view, the majority of the triggers \nwill be non-GRBs.  While this is probably not a problem for the \nautomated instrument GCN sites, those sites that involve human effort \nand/or consumables must understand that many of the HETE Notices will \nbe non-GRBs (eg x-ray bursters, soft gamma repeaters, flaring \ngalactic sources, etc).\n\nIn general, there will also be follow-up GCN Circulars disseminated \nfor HETE burst events which prove to be confirmed GRBs.  These \nfollow-up Circulars will be based on detailed telemetry data which \nbecomes available on the ground 1-2 orbits after the burst, so such \nHETE Circulars will lag the HETE Notices by a few hours.\n\nAll those sites who have requested the HETE Notices to be enabled \nneed do nothing.  They will receive them.  If sites wish to change \ntheir configuration, then please send a request.",
