Abstract
The 19th solar cycle was characterized by abnormally high solar activity; unfortunately, the possibilities of observing it were limited. Ground-based observations of cosmic rays and geomagnetic activity are among the few types of continuous measurements that allow statements about the events of 19th cycle and their comparison with events of other cycles. Comparison of the events in cosmic rays with solar and geomagnetic activities shows that the number and strength of magnetic storms in the 19th cycle correspond to an abnormally high number of sunspots. However, large Forbush decreases were lacking in this cycle. The most powerful ICMEs of the 19th cycle were generally weaker than the greatest ones in later periods.
