A preliminary triangulation gives a long,\nnarrow error box centered at RA, Dec = 119.830, -56.790 degrees\n(0.2 degrees from the center of the LAT error circle), whose\ncorners are:\n\n RA(2000)    DEC(2000)             \n  119.486    -62.130\n  120.126    -62.702\n  119.901    -50.632\n  120.321    -51.274\n\nA figure is posted at ssl.berkeley.edu/ipn3/080916C.\n\nUsing the RHESSI data between 100 keV and 17 MeV, the time-integrated\nspectrum for the 62-second interval beginning at 00:12:46 UT can be described\nby a cutoff power law with alpha ~ -1.2 +/- 0.3, Epeak ~ 1100 +/- 500 keV,\nand fluence ~ (9.0 +/- 1.6) x 10^-5 ergs/cm^2 (100 keV - 10 MeV).\n\n\nBoth the triangulation and the energy spectrum can be substantially\nimproved.",
