Goldstein (UAH) reports on behalf of the Fermi GBM Team: \n\n\"At 21:12:07.73 UT on 10 June 2009, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 090610C (trigger 266361129 / 090610883).\n\nThe on-ground calculated location, using the GBM trigger \ndata, is RA = 70.4, DEC = +30.3 (J2000 degrees, \nequivalent to 04h 42m, 30d 18'), with an uncertainty \nof 8.2 degrees (radius, 1-sigma containment, \nstatistical only; there is additionally a systematic\nerror which is currently estimated to be 2 to 3 degrees).\nThe angle from the Fermi LAT boresight is 104 degrees.\n\nThe GBM light curve consists of a single pulse\nwith a duration (T90) of about 18.1 s (8-1000 keV). \nThe time-averaged spectrum from T0-4.1 s to T0+8.2 s is \nbest fit by a simple power law function with index -1.62 +/- 0.08\n(chi squared 341.6 for 362 d.o.f.).\n\nThe event fluence (8-1000 keV) in this time interval is \n(8.54 +/- 0.38)E-07 erg/cm^2. The 1-sec peak photon flux \nmeasured starting from T0-0.51 s in the 8-1000 keV band \nis 1.12 +/- 0.11 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary; \nfinal results will be published in the GBM GRB Catalog.\"",
