Bala (USRA) report on behalf of\nthe Fermi Gamma-ray Burst Monitor Team:\n\n\"At 01:18:28.51 UT on 26 March 2026, the Fermi Gamma-ray Burst Monitor (GBM)\ntriggered and located GRB 260326A (trigger 796180713/260326054). \nThe Fermi GBM real-time Localization is reported in GCN 44115.\n\nThe angle from the Fermi LAT boresight is 76 degrees.\n\nThe GBM light curve consists of two spikes from a single emission episode with a duration (T90)\nof about 50 s (50-300 keV). The time-averaged spectrum\nfrom T0-6.0 to T0+66.0 s is best fit by\na Band function with Epeak = 275 +/- 1 keV,\nalpha = -1.040 +/- 0.004, and beta = -2.00 +/- 0.01.\n\nThe event fluence (10-1000 keV) in this time interval is\n(5.37 +/- 0.05)E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+7.0 s in the 10-1000 keV band is 32.6 +/- 0.4 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog:\nhttps://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigbrst.html\n\nFor Fermi GBM data and info, please visit the official Fermi GBM Support Page:\nhttps://fermi.gsfc.nasa.gov/ssc/data/access/gbm/\"",
