GCN 1258 02/03/02 18:10:19 GMT Konus-Wind and Ulysses observed an exceptional gamma-ray transient on February 24 whose duration was over 10,000 seconds. It began around 15:00 UT and came from a source with high north ecliptic latitude. Triangulation gives an annulus centered at RA 260.443, DEC +78.208, with radius 46.138 +/- 1.215 degrees. This localization is inconsistent with a solar origin, and the error box excludes all ... IPN triangulation of GRB 020305 (HETE 1939) Hurley et al. GCN 1263 02/03/06 19:01:57 GMT Ulysses observed GRB 020305 (HETE 1939). As observed by both Ulysses and FREGATE, this event consists of two distinct episodes of emission separated by an ~ 200 s long quiescent period, raising the question of whether both episodes are from the same source. As the Ulysses and FREGATE time histories are identical to within statistics, we conclude that both episodes indeed had the same origin ... IPN localization of GRB 020405 Hurley et al.

GCN 1396 02/05/27 23:19:13 GMT Two short bursts were detected on May 25 which, due to their proximity in time to an earlier burst from SGR1806-20 (see GCN 1391), may also be from this SGR. The first was at ~16014 s and was observed by Konus-Wind; the second was detected by Ulysses and was at 43615 s (Ulysses time; the spacecraft was ~1850 light-seconds from Earth). If the second event came from SGR1806-20, its Earth-crossing ... IPN triangulation of the short, hard GRB 020531 (HETE 2042) Hurley et al.
