Abstract: An attempt has been made to select about 33 Forbush type decreases occurring during 1986-1999 at Kiel Neutron Monitor Station. This interval covered the whole period of sunspot solar cycle 22 and ascending part of solar cycle 23. Recovery time characteristics of Forbush decreases are studied. The average recovery time of neutron monitor energies is 4 days, but varies from 2 to 10 days. No significant difference in the average recovery time is observed from two different rigidities. The relative amplitudes of these decreases are examined.
