Solar storms

Through the SWAN instrument carried by the SOHO satellite it has been discovered that sunspots emit ultraviolet rays. Consequently, it is possible to know the activity of the spots on the side of the Sun that is not seen at that time. Stains, on the other hand, occur as a result of solar storms and occasionally interfere in the terrestrial or communications grid.
