Solar cycle 8 was the eighth solar cycle since 1755, when extensive recording of solar sunspot activity began.[1][2] 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, and the minimum was 10.6.[3]
Solar cycle #8 ended in 1843, the year that Heinrich Schwabe discovered the sunspot cycle.[4]
