    Solar flux is a measurement of the intensity of solar radio emissions with a wavelength of 10.7 cm (a frequency of about 2800 MHz).
    The value broadcast is in solar flux units that range from a theoretical minimum of about 50 to numbers larger than 300.
    The A and K indices are a measurement of the behavior of the magnetic field in and around the earth.
    The K index uses a scale from 0 to 9 to measure the change in the horizontal component of the geomagnetic field.
