title: Solar proton events at the growth phase of the 22nd solar activity cycle.
abstract: Meteor satellite observations in March, August, September and October 1989 recorded intensive solar proton events which caused a disturbed radiation situation in the near-Earth space.  The paper presents the results of analyzing flux and spectral characteristics of the events and their relation to heliogeophysical situation.
