http://www.solen.info/solar/http://www.solen.info/solar/cyclcomp.htmlsolar cycle 24 has initially displayed much less activity than recent cycles. based on statistical models the monthly smoothed sunspot number is likely to peak between 50 and 70 in 2013. models based on solar polar magnetic field strength indicate the peak could occur as early as in 2012. the comparison with recent cycles is interesting to track the development of cycle 24. the x axis in the chart is the number of months since the cycle started, while the y axis is the monthly smoothed sunspot number.
