Abstract

In recent years, radio observations of solar emission at 10.7cm wavelengths show a systematic increase compared to the sunspot number (SSN). The 10.7cm solar radio flux (F10.7) is one of the most widely used indices of solar activity. The solar magnetic field flux measured for the entire solar cycle is compared with the solar index of the effective cycles for the years 1986-2015. The solar activity indices include numerous quantities. Of these indices the two most used are the relative sunspot number, covering more than 300 years and the 10.7cm solar radio flux (F10.7), which has been measured regularly since 1947. The data published in the official website of National Oceanic and Atmospheric Administration (NOAA) has been used in the analysis. This study examines the relative sunspot number and 10.7cm solar radio flux indices individually and also the relation between them, and also what it implies on the solar behaviour for the solar cycle 22, 23 & 24.
