Bissaldi (MPE) and A. von Kienlin (MPE)\nreport on behalf of the Fermi GBM Team:\n\n\n\"At 14:52:42.17 UT on 06 February 2009, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 090206 (trigger 255624764 / 090206620).\nThe on-ground calculated location, using the GBM trigger\ndata, is RA = 157.2, DEC = +14.5 (J2000 degrees,\nequivalent to 10h 29m, 14d 30'), with an uncertainty\nof 8.7 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 72 degrees.\n\nThis burst was also independently detected by INTEGRAL SPI-ACS.\n\nThe GBM light curve consists of a single peak\nwith a duration (T90) of about 0.8 s (8-1000 keV).\nThe time-averaged spectrum from T0-0.064 s to T0+0.512 s is\nadequately fit by a power law function with an exponential\nhigh energy cutoff.  The power law index is -0.65 +/- 0.14 and\nthe cutoff energy, parameterized as Epeak, is 710 +/- 170 keV\n(chi squared 402 for 456 d.o.f.).\n\nThe event fluence (8-1000 keV) in this time interval is\n(1.04 +/- 0.06)E-06 erg/cm^2. The 64-msec peak photon flux\nmeasured starting from T0 in the 8-1000 keV band is\n19.0 +/- 1.0 ph/s/cm^2.\n\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
