at Ooty (N11.4 , E76.7 and 2200m altitude). The muon detector has an area of 560 m and threshold energy of 1.0 GeV. Due to large detector size, a very large number of muons, , per hour are detected. The design of the muon detector allows simultaneous measurement of muon intensity from 225 directions. Therefore it enables us to make a 2-dimensional map of intensity variation of cosmic ray with energy of GeV. In general, due to a higher median rigidity of the response, the muon telescope can detect small scale anisotropy more precisely as compared to a neutron monitor. It is also useful for space weather forecasting. Here we analyze the cosmic ray storm events observed during the period, 2001-2002. A number of Loss-Cone Precursor decreases were detected during this period. The association rate for Forbush decrease (Fd) and correlation with magnitude of Fd are also discussed. 1
