Zonneflux
Zonneflux, also known as solar flux, is a measure of the sun's brightness as observed at the wavelength of 10.7 cm on the radio spectrum. It is a key indicator of solar activity and is used to monitor the sun's behavior and predict space weather. The solar flux is typically measured in solar flux units (sfu), where 1 sfu is equal to 10^-22 watts per square meter per hertz.
The solar flux is influenced by the number of sunspots on the sun's surface. Sunspots are cooler,
The solar flux is an important parameter for various fields, including space weather forecasting, radio communication,
