Abstract. A catalog of type II bursts and the associated coronal mass ejections (CMEs) observed by the solar and heliospheric observatory (SOHO) mission is used to select the twenty three CMEs events with CME speed equal to and less than 450 Km/Sec (i.e less than and equal to the average solar wind speed) during 1997-2008. Our observational results clearly indicate the even slow speed CMEs are capable of producing the cosmic ray and geomagnetic disturbances on day to day basis. The depression in cosmic ray intensity is larger three days after the arrival of the CMEs and is associated with the maximum disturbance in geomagnetic activity on the same day (i.e after three day from the arrival of CMEs). Fluctuations in cosmic ray intensity and the geomagnetic activity is also observed before the arrival of the CMEs.
