odulations of cycles F S Festerov has reported the spectru of Solar radio eissions at )$(5 .9$ Hs #ell as sho#ing coon periods of 154 and (( days" there is cople spectral structure around each of these periods suggesting odulation by longer cycles$ enerally reports indicate that the cycles are stronger near solar aiu" so these odulations ay be due to the ain 11 year solar cycle$ The analysis is based on
.aronic Relationships in Solar cycles F$ H$ ;rivova and S$ ;$ Solan6i note that the po#er of a 1$2' year sunspot cycle period varies strongly over tie but does vary approiately in phase #ith the 15* day Rieger period of Solar flares$ This result based on #avelet analysis suggests that these t#o cycles are haronics because 1$2' years is ) ties 15* days$ They find that this period of 15* days continues into ore recent cycles in contrast to earlier results$ They also report significant po#er at all ultiples of 1$) years +reported as 1$2' years above, up to 10$4 years$ They note also that the 15* day period is found in sunspot nubers and that the 1$) year period is found in variations of geoagnetic activity and interplanetary agnetic field$ any researchers have noted the haronic relationships in the solar periods$ 8ai and Sturroc6 coent that the 154 day and related periodicities are sub!haronics of a fundaental period$ hen all the reports are cobined it is even clearer that all the reported periods are haronically related to each other$ The solar cycle periods are observed in geophysical cycles on 3arth and also haronically related to other coonly observed cycles on earth fro other disciplines$ The follo#ing table has been produced #ith eact ratios of 2 and ) to best fit all the 6no#n cycles periods$ It is clear that this produces another #hole set of related cycles li6e e#ey>s table of coon cycles in the range of years$ %urtherore" these cycle periods are related by being a factor of ( saller than e#ey>s table$
