Takahashi (ICRR University of Tokyo), on behalf of the MAGIC collaboration report:\n\nOn December 16, 2020, the MAGIC telescopes observed GRB 201216C following the\ntrigger by Swift-BAT and Fermi-GBM (Beardmore et al., GCN 29061, Fermi/GBM team GCN 29063).\nMAGIC started observations under good conditions about 57 seconds after the GRB onset.\nThe preliminary offline analyses show an excess above 5 sigma, compatible with the GRB position reported\nby the Swift and Fermi teams. Refined off-line analyses of the data are ongoing.\n\nWe strongly encourage follow-up observations by other instruments at all wavelengths.\n\nThe MAGIC point of contact for this burst is O. Blanch (blanch@ifae.es). \nBurst Advocate for this burst is F. Longo (francesco.longo@ts.infn.it).\n\nMAGIC is a system of two 17m-diameter Imaging Atmospheric Cherenkov Telescopes\nlocated at the Observatory Roque de los Muchachos on the Canary island\nLa Palma, Spain, and designed to perform gamma-ray astronomy in the energy\nrange from 50 GeV to greater than 50 TeV.\n\n\n-- \nAv�s -\nAviso - Legal Notice - (LOPD) - http://legal.ifae.es \n<http://legal.ifae.es/>",
