HETE2GRB - HETE-2 Gamma-Ray Bursts



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 the burst summary web pages created at MIT at the The HEASARC table will be updated on a twice-per-week basis shortly after whenever the MIT web pages are updated.


The HETE2GRB database table summarizes the gamma-ray bursts that have been identified by HETE-2.
