Solar activity has been on a declining trend since the 1960s, as indicated by solar cycles 19–24, in which the maximum number of sunspots were 201, 111, 165, 159, 121 and 82, respectively. [14] In the three decades following 1978, the combination of solar and volcanic activity is estimated to have had a slight cooling influence. [ 15 ]

The level of solar activity beginning in the 1940s is exceptional – the last period of similar magnitude occurred around 9,000 years ago (during the warm Boreal period). [ 11 ] [ 12 ] [ 13 ] The Sun was at a similarly high level of magnetic activity for only ~10% of the past 11,400 years.
Sun path, sometimes also called day arc, refers to the daily (sunrise to sunset) and seasonal arc-like path that the Sun appears to follow across the sky as the Earth rotates and orbits the Sun. The Sun's path affects the length of daytime experienced and amount of daylight received along a certain latitude during a given season.
Solar cycle 24 is the most recently completed solar cycle, the 24th since 1755, when extensive recording of solar sunspot activity began. [ 1 ] [ 2 ] It began in December 2008 with a minimum smoothed sunspot number of 2.2, [ 3 ] [ failed verification ] and ended in December 2019. [ 4 ]
