"At 14:52:42.17 UT on 06 February 2009, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 090206 (trigger 255624764 / 090206620). The on-ground calculated location, using the GBM trigger data, is RA = 157.2, DEC = +14.5 (J2000 degrees, equivalent to 10h 29m, 14d 30'), with an uncertainty of 8.7 degrees (radius, 1-sigma containment, statistical only; there is additionally a systematic error which is currently estimated to be 2 to 3 degrees). The angle from the Fermi LAT boresight is 72 degrees. This burst was also independently detected by INTEGRAL SPI-ACS. The GBM light curve consists of a single peak with a duration (T90) of about 0.8 s (8-1000 keV). The time-averaged spectrum from T0-0.064 s to T0+0.512 s is adequately fit by a power law function with an exponential high energy cutoff. The power law index is -0.65 +/- 0.14 and the cutoff energy, parameterized as Epeak, is 710 +/- 170 keV (chi squared 402 for 456 d.o.f.). The event fluence (8-1000 keV) in this time interval is (1.04 +/- 0.06)E-06 erg/cm^2. The 64-msec peak photon flux measured starting from T0 in the 8-1000 keV band is 19.0 +/- 1.0 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
