GCN Circular 22079
R. Hamburg (UAH) and C. Meegan (UAH) report on behalf of the Fermi GBM Team: "At 17:29:45.12 UT on 30 October 2017, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 171030A (trigger 531077390 / 171030729) which was also detected by Swift/BAT and INTEGRAL/SPI-ACS, as reported by the Interplanetary Network (GCN 22076). The GBM on-ground location is consistent with the Swift/BAT location (GCN 22078). The angle from the Fermi LAT boresight at the GBM trigger time is 135 degrees. The GBM light curve shows a single peak with a duration (T90) of about 0.1 s (50-300 keV). The time-averaged spectrum from T0-0.06 s to T0+0.00 s is adequately fit by a simple power law function with index -1.11 +/- 0.07. The event fluence (10-1000 keV) in this time interval is (1.7 +/- 0.2)E-07 erg/cm^2. The 0.064-sec peak photon flux measured starting from T0-0.064 s in the 10-1000 keV band is 11.6 +/- 2.2 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
