Solar cycle 8 was the eighth solar cycle since 1755, when extensive recording of solar sunspot activity began. The solar cycle lasted 9.8 years, beginning in November 1833 and ending in July 1843. The maximum smoothed sunspot number (monthly number of sunspots averaged over a twelve-month period) observed during the solar cycle was 146.9 (March 1837), and the minimum was 10.6.
Solar cycle #8 ended in 1843, the year that Heinrich Schwabe discovered the sunspot cycle.
