 note = {Time series of satellite image data for SOHO/MDI Continuum and Magnetogram from 1997 to 2010, and for SDO/HMI Continuum and Magnetogram from 2011 to 2012 are analyzed. The occupancies of sunspot pixels in Continuum and of pixels for positive and the negative magnetic polarities in Magnetogram are calculated. By box-counting method, packing exponents for sunspot pixels in Continuum and packing exponents for positive polarity pixels and negative polarity pixels in Magnetogram are evaluated. Packing exponents of Continuum and Magnetogram from 1997 to 2012, power spectra with peaks are calculated by using Fourier transform, respectively. A first peak of the power spectra is determined, and time intervals between nearest neighbor peaks are valued. The behavior of the packing exponents represented with time series are discribed in detail and discussed., 紀要論文},
