| Abstract: | During the sunspot minimum years 2007-2009 of solar cycle 23, the sunspot
number, Rz, declined from January 2007 till the end of 2007 and further till
September 2009. But in between, there were sporadic increases during January,
June, December 2007; March 2008; and September 2009. These were reflected very
well in timing in the 2800 MHz solar radio emission flux F-10, X-ray
background, and the occurrence frequency of coronal mass ejections (CME). Thus,
all these have a major origin in the same active regions. |
