Solar radio flux - plot of rotational averages
For an accessible version of the rotational averages, please view the Rotational Averages (HTML version).

The rotational averages are the radio emission from the Sun at a wavelength of 10.7 centimetres averaged over the Carrington Rotation. Vertical scale units are in solar flux units (1 sfu = 10-22.m-2.Hz-1), horizontal units are Carrington Rotation number. Carrington Rotation Number is the number of times the Sun has rotated since 9th November, 1853. The rotation period is roughly 27 days.
