For an accessible version of the monthly averages, please view the Monthly Averages (HTML version).

The monthly averages are the radio emission from the Sun at a wavelength of 10.7 centimetres averaged over the month. Vertical scale units are in solar flux units (1 sfu = 10^-22 W m^-2 Hz^-1), horizontal scale units are in years.
