Moretti (IFAE-BIST Barcelona)\nreport on behalf of the Fermi-LAT Collaboration:\n\n\nFermi-LAT observed the position of GRB 201216C, which was detected\nby Fermi-GBM (GCN Circ. 29073), Swift (GCN Circ. 29061, 29064),\nand MAGIC (GCN Circ. 29075).\nThe GRB position was not in the LAT field of view at the time\nof the GBM trigger (T0 = 2019-12-16, 23:07:25.75 UT), and was not visible\nuntil ~T0+3500 s. The position remained visible until ~T0+5500 s.\n\nNo significant high-energy gamma-ray emission associated with this burst\nwas detected by the LAT in this time interval.\n\nA LAT upper limit (95% confidence level, 100 MeV - 1 GeV), assuming a\nphoton index of -2.0, covering the same time interval is 7.3E-7 ph/s/cm2.\nThe corresponding upper limit for energy flux is 3E-10 erg/s/cm2.\n\nThe Fermi-LAT point of contact for this burst is\nElena Moretti (moretti@ifae.es).\n\n\nThe Fermi-LAT is a pair conversion telescope designed to cover\nthe energy band from 20 MeV to greater than 300 GeV.\nIt is the product of an international collaboration between\nNASA and DOE in the U.S. and many scientific institutions\nacross France, Italy, Japan and Sweden.",
