    • HETE-2 GCN Triggers Catalog

    Metadata Updated: March 13, 2026

    HETE-2 (the High Energy Transient Explorer) is an international mission designed to help unravel the mystery of Gamma-Ray Bursts (GRBs). The primary goal of HETE-2 is to determine the origin and nature of cosmic gamma-ray bursts (GRBs) by simultaneous observation of soft and medium X-rays and gamma-rays to provide precise localization of GRBs and identification of counterparts to these explosions. HETE-2 carries three science instruments: a set of wide-field gamma-ray spectrometers (FREGATE), a wide-field X-ray monitor (WXM, and a set of soft X-ray cameras (SXC) HETE-2 was launched on October 9, 2000, and declared fully operational on February 6, 2001. The contents of this HEASARC database table are based on online tables created by Scott Barthelmy and available at the <a href="http://gcn.gsfc.nasa.gov/">http://gcn.gsfc.nasa.gov/</a>; web site. The HEASARC table will be updated on a twice-per-week basis whenever the original tables are updated. This is a service provided by NASA HEASARC .
