Solar soft X-ray variations in 22^{nd} and 23^d solar cycles
Abstract
The oscillations in solar daily soft X-rays (SXR) have been analyzed for 22^{nd} and 23^d solar cycles. The SXR in the 1-8Å passband have been recorded by the GOES-6,8 satellites from January 1986 to April 2003 year. For 22^{nd} cycle the revealed periodicities 24, 43, 54, 65 and 73 days coincide with the 23^d cycle ones within data uncertainty (1 day) and their values may be explained by the differential rotation of the solar chromosphere and corona.
