Keywords:cosmic ray observations, Forbush Decrease, cosmic ray anisotropy

Following a series of solar eruptions, a large Forbush Decrease accompanied by significant cosmic ray anisotropy has been observed on November 4, 2021 with global networks of neutron monitors and muon detectors. In this report, we discuss the preliminary results of our analyses of these cosmic ray data.
