Solar cycle 5 was the fifth solar cycle since 1755, when recording of solar sunspot activity began.[1][2] The solar cycle lasted 12.6 years, beginning in May 1798 and ending in December 1810. The maximum smoothed sunspot number (monthly number of sunspots averaged over a twelve-month period) observed during the solar cycle was 49.2, and the minimum was zero.[3]
