Abstract
:
The eleven-year sunspot cycles are considered to represent one of the solar activities. The daily observations of the sunspots in the KAAU Solar Observatory (KAAUSO) have been utilised to reduce a period of the present solar cycle, using Fourier technique. The highest peak in the amplitude spectrum was for a frequency of 0.00029 day-1, for which the maximum occurred mid 1990.
