Briggs (UAH)\nreports on behalf of the Fermi GBM Team:\n\n\"At 15:10:49.48 UT on 26 March 2009, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 090326 (trigger 259773051 / 090326633).\n\nThe on-ground calculated location, using the GBM trigger\ndata, is RA = 259.6, DEC = -11.6 (J2000 degrees,\nequivalent to 17 h 18 m, -11 d 36'), with an uncertainty\nof 1.8 degrees (radius, 1-sigma containment,\nstatistical only; there is additionally a systematic\nerror which is currently estimated to be 2 to 3 degrees).\n \nThe angle from the Fermi LAT boresight is 103 degrees.\n\nThe GBM light curve shows two peaks\nwith a duration (T90) of about 11.2 s (8-1000 keV).\nThe time-averaged spectrum from T0-3.072 s to T0+10.240 s is\nwell fit by a power law function with an exponential\nhigh energy cutoff.  The power law index is -0.86 +/- 0.22 and\nthe cutoff energy, parameterized as Epeak, is 75. +/- 8. keV.\nThe fluence in this time interval is (8.6 +/- 1.8)E-07 erg/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
