TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1233 SUBJECT: IPN detection of further activity from SGR1806-20 DATE: 02/01/29 00:34:27 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley, on behalf of the Ulysses GRB team, E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team, and C. Guidorzi, E. Montanari, F. Frontera, and M. Feroci, on behalf of the BeppoSAX GRBM team, report: The IPN continues to detect activity which is probably from SGR1806-20. The updated event list is now: DATE TIME ULYSSES BEPPOSAX KONUS ____ ____ _______ ________ _____ 020117 81788 YES IN SAA WEAK RESPONSE 020118 71671 YES YES YES 020122 38499 YES NO DATA YES 020124 79251* YES 020125 36444* YES *TIME AT ULYSSES, WHICH WAS ABOUT 1250 LIGHT-SECONDS FROM EARTH; EARTH-CROSSING TIME FOR SGR1806 IS ABOUT 75 S LATER The bursts on the 17th, 18th, and 22nd have all been triangulated to annuli which are consistent with the position of SGR1806. The bursts on the 24th and 25th are definitely SGR-like, in that their durations are ~30 ms; there are too few photons in the Ulysses data to determine their spectra, however. We are searching for confirmation of them in the GRBM and KONUS data, which will allow triangulation.
