[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] Activity was minimal until early 2010. [ 5 ] [ 6 ] It reached its maximum in April 2014 with a 23 months smoothed sunspot number of 81.8. [ 7 ]
Solar maximum is the regular period of greatest solar activity during the Sun's 11-year solar cycle. During solar maximum, large numbers of sunspots appear, and the solar irradiance output grows by about 0.07%. [2] On average, the solar cycle takes about 11 years to go from one solar maximum to the next, with duration observed varying from 9 to ...

In 2024, the sun enters its solar maximum—birds don't know what's about to hit them. Space weather may seriously send their internal compasses into disarray. In 2024, the sun enters its solar ...
Solar cycle 25 is the current solar cycle, the 25th since 1755, when extensive recording of solar sunspot activity began. It began in December 2019 with a minimum smoothed sunspot number of 1.8. [2] It is expected to continue until about 2030. [3] [4]
