GCN Circular 24692
E. Bissaldi (Politecnico & INFN Bari) and C. Meegan (UAH) report on behalf of the Fermi GBM Team: "At 10:19:08.90 UT on 30 May 2019, the Fermi Gamma-Ray Burst Monitor (GBM) triggered and located GRB 190530A (trigger 580904353 / 190530430, GCN #24676), which was also detected by AGILE-MCAL (GCN # 24678) and Fermi-LAT (GCN # 24679). The GBM light curve consists of multiple bright peaks with a duration (T90) of about 18.4 s (50-300 keV). The time-averaged spectrum from T0 to T0+20 s is adequately fit by a Band function with Epeak = 900 +/- 10 keV, alpha = -1.00 +/- 0.01, and beta = -3.64 +/- 0.12. The event fluence (10-1000 keV) in this time interval is (3.72 +/- 0.01)E-04 erg/cm^2. The 1-sec peak photon flux measured starting from T0+16.4 s in the 10-1000 keV band is 160.5 +/- 0.7 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/"
