Number of large SEP events as a function of time from September 1995 to the end of April 2014. The black, red, and blue plots denote cycles 22, 23, and 24, respectively. The right-point arrow within the cycle-23 interval corresponds to the first 66 months of cycle 23 (May 1996 to November 2001) used for comparing with the current length of cycle 24 (December 2008 to April 2014). The first large SEP event occurred only in August 2010.
