Third weakest solar cycle since 1755

A recent publication has analyzed the current solar cycle and has found that when sunspot anomalies are compared to the mean for the number of months after cycle start, there have been only two weaker cycles since observations began in 1755.  Solar cycle 24 began in 2008 after a historically long and deep solar minimum which puts us more than eight years into the current cycle.
