HETE Bursts

The HETE Bursts page contains information about HETE bursts.

In the frame on the left, you'll find links to pages with data about particularly interesting bursts.

The Table of HETE Fregate Archival Data for Localized Bursts are available at http://space.mit.edu/Bursts/Data. The data archives now include a list of answered questions from the astronomical community

The burst summary page shows comments about each burst, written soon after each burst by the HETE Duty Scientist.

The Alerts page gives information about real-time triggering and burst imaging as well as a description of the GCN messages distributed after each burst.

GRB 050709 = Trigger 3862

HETE detected and localized the short/hard GRB 050709. followup observations with Chandra, Hubble, and ground-based telescopes reveal a fading counterpart at z = 0.16!! This is the first time a redshift has been determined for a short/hard burst.

GRB 050408 = Trigger 3711

GRB 050408 was localized in real time by both the WXM and SXC on HETE. The burst was promptly followed up with the Swift XRT. An optical counterpart was found at a redshift of 1.24.
