Wavelet Analysis of The Photospheric Magnetic Flux

We present a time sequence of photospheric magnetic flux in high temporal resolution by connecting the Kitt Peak synoptic charts from Carrington rotation cycle 1666 to 1985. Wavelet analysis of this sequence shows that some short periods occurred during the whole time, such as 156d, 306d, 1.3yr, 2.6yr, 5yr, and so on. The time-variation and mutual relations of these periods are discussed in detail. We also analyze the periodicity in the solar total irradiance with the same method and some comparative work is performed.
