An example is the Meeus smoothing formula, [7] with related solar cycles characteristics available in this STCE news item. [ 8 ] The start of solar cycle 25 was declared by SIDC on September 15, 2020 as being in December 2019. [ 9 ]
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 ...
Scientists said the sun is now in its solar maximum, or the peak of its 11-year solar cycle.
