The Sun with some sunspots visible.

Solar cycle 16 was the sixteenth solar cycle since 1755, when recording of solar sunspot activity began.[1][2] The solar cycle lasted 10.1 years, beginning in August 1923 and ending in September 1933. The maximum smoothed sunspot number (monthly number of sunspots averaged over a twelve-month period) observed during the solar cycle was 78.1, and the minimum was 3.5.[3] There were a total of 568 days with no sunspots during this cycle.[4][5][6]
