Krimm, on behalf of\nthe Swift-BAT team, report:\n\nMars Odyssey (GRS), Konus-Wind, Suzaku-WAM, INTEGRAL SPI-ACS,\nAGILE-MCAL, SuperAGILE, and Swift-BAT observed the long-duration, hard \nspectrum GRB 080204 at about 50192 s UT (13:56:32). The burst was \noutside the coded field of view of the BAT and SuperAGILE.\nThe burst light curve shows a short precursor, followed in ~3 sec by a \nsingle multipeaked pulse with a duration of ~15 sec. There is a sign of \nextended emission seen up to T-T0~80 s in the Konus-Wind soft band.\n\nWe have triangulated the burst to the following, preliminary 3-sigma\nerror box:\n-----------------------------------------------\n    RA(2000), deg             Dec(2000), deg\n-----------------------------------------------\nCenter:\n  285.566 (19h 02m 16s)   -62.896 (-62d 53' 44\")\nCorners:\n  287.728 (19h 10m 55s)   -62.334 (-62d 20' 01\")\n  283.813 (18h 55m 15s)   -63.453 (-63d 27' 12\")\n  283.277 (18h 53m 07s)   -63.402 (-63d 24' 08\")\n  287.212 (19h 08m 51s)   -62.305 (-62d 18' 18\")\n-----------------------------------------------\n\nThe error box area is 1212 sq. arcmin.\nThis error box may be improved\n\nPreliminary analysis of the Konus-Wind data yields\na burst fluence of ~4x10^-5 erg/cm2 (in the 20 keV - 4 MeV range),\nand a very hard energy spectrum with an Epeak of the main pulse\nof ~1.4 MeV.\n\nDetailed spectral parameters will be reported later.",
