The Solar Cycle 25 Prediction Panel predicted in December 2019 [11] that solar cycle 25 will be similar to solar cycle 24, with the preceding solar cycle minimum in April 2020 (± 6 months), and the number of sunspots reaching a (smoothed) maximum of 115 in July 2025 (± 8 months). This prediction is in line with the current general agreement ...
Solar cycle expectations for 2025 The year 2024 was huge for solar news. In April, a total solar eclipse was visible to millions of Americans, which was then followed by multiple widespread ...
As at Feb 20, 2025, solar cycle 25 is averaging 37% more spots per day than solar cycle 24 at the same point in the cycle (Feb 20, 2014). Year 1 of SC25 (Dec 2019 to Nov 2020) averaged 101% more spots per day than year 1 of SC24.
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 ...
Solar seasons play out not over the course of months, however, but in 11-year cycles that produce times of high activity, known as the solar maximum, and low activity known as the solar minimum.
Now that the sun has reached its solar maximum, aurora chasers should expect the northern lights to appear more frequently in the night sky. Amid solar maximum, northern lights should flourish ...
As the sun reaches the height of its 11-year cycle, skygazers may only be treated to better and more frequent chances to witness the northern lights.
This total solar eclipse had a maximum duration of 6 minutes and 38.86 seconds. The longest possible duration of a total solar eclipse is 7 minutes and 32 seconds. The longest annular solar eclipse of the 21st century took place on January 15, 2010, with a duration of 11 minutes and 7.8 seconds. The maximum possible duration is 12 minutes and ...
