GCN Circular 26627
P. Veres and C. Meegan (both UAH) report on behalf of the Fermi GBM Team: "At 20:39:26.45 UT on 1 January 2020, the Fermi Gamma-Ray Burst Monitor (GBM) triggered and located GRB 200101A (trigger 599603971 / 200101861). The location for this GRB was reported in the Fermi GBM Final Real-time Localization GCN (GCN 26624). The GBM light curve shows of multiple pulses with a duration (T90) of about 10 s (50-300 keV). The time-averaged spectrum from T0+3.3 s to T0+19.8 s is best fit by a Band function with Epeak = 595 +/- 13 keV, alpha = -0.82 +/- 0.01, and beta = -2.15 +/- 0.03. The event fluence (10-1000 keV) in this time interval is (9.38 +/- 0.05)E-5 erg/cm^2. The 1-sec peak photon flux measured starting from T0+11.5 s in the 10-1000 keV band is 124.8 +/- 0.6 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog: https://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigbrst.html For Fermi GBM data and info, please visit the official Fermi GBM Support Page: https://fermi.gsfc.nasa.gov/ssc/data/access/gbm/"
