摘要:

The present gamma-ray burst (GRB) network consists of the Ulysses and the Near Earth Asteroid Rendezvous missions in deep space, with the BATSE experiment on Compton-GRO, the Konus experiment on GGS-Wind, and the BeppoSAX mission all near to the Earth. The NEAR spacecraft, built and launched without any GRB capability, was modified in flight to provide 1-second GR count rates, creating the first 3-cornered long-baseline IPN since the early 1990s. The arc-minute precision of this IPN was confirmed with the known locations of SGRs and GRB afterglows. After the Eros orbital insertion maneuver was postponed until February 2000, the NEAR spacecraft was placed in a low bit-rate, dormant mode, but was dedicated to GR data by command. Most events are now saved, although data recovery is necessarily delayed up to several days. Restoration to the active mode is expected in January 2000. Note: since the Huntsville Symposium, the first all-IPN alert to result in radio and/or optical afterglow observations followed GRB991208. ©2000 American Institute of Physics.
