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.
