Abstract
Sunspots have a major 11year cycle but the three to four years near the maximum may show two or more peaks called Gnevyshev peaks Earlier it was reported that in Solar Cycle 23 the double peak in sunspot numbers was reflected in the electromagnetic radiations and coronal mass ejection CME frequencies in the solar atmosphere but with phase differences In this article it is shown that the average CME speeds also show Gnevyshev peaks but with phase differences
