Biland (ETH Zurich) reports on behalf of the FACT Collaboration:\n\nAMON and ANTARES announced on Oct 14th the identification of the\ncoincidence of a high-energy neutrino with a Fermi-LAT photon on Oct\n11th 15:54:32 UTC from a position close to the blazar RBS 0413.\n\nDue to safety constraints and not ideal weather conditions, FACT\nstarted observing RBS 0413 only in the night from Oct 17th to Oct 18th.\nDuring this night, only 10 minutes of data have been taken due to not\nideal weather conditions. During the following night, another 170\nminutes of data have been taken.\n\nThe automatic quick-look analysis does not show any signal from the\nobserved position. Preliminary results can be found at\nhttps://fact-project.org/monitoring/index.php?y=2019&m=10&d=18&source=3261&timebin=12&plot=week\n\n From the results of the quick-look analysis, an upper limit of 20% of\nthe flux of the Crab Nebula at TeV energies was determined with a\nconfidence level of 99%.\n\nContact person: Daniela Dorner (dorner@astro.uni-wuerzburg.de)\n\nThe First G-APD Cherenkov Telescope (FACT) is an imaging air Cherenkov\ntelescope monitoring blazars at TeV energies. It is located in the\nObservatorio del Roque de los Muchachos on the Canary Island La Palma.",
