COSMIC RAYS AND THE SOLAR CYCLE
Solar activity rises and falls with a
period of about 11 years. The number of sunspots indicates the
level of solar activity.
Emissions of matter and electromagnetic fields
from the Sun increase during high solar activity, making it harder for
Galactic cosmic rays to reach Earth. Cosmic ray intensity is lower when
solar activity is high.
Solar activity is currently low, and the cosmic
ray intensity is high. Soon the sunspots will increase
and cosmic ray intensity will start to decrease.
