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 ...
As at Jan 3, 2025, solar cycle 25 is averaging 39% more spots per day than solar cycle 24 at the same point in the cycle (Jan 3, 2014). Year 1 of SC25 (Dec 2019 to Nov 2020) averaged 101% more spots per day than year 1 of SC24. Year 2 of SC25 (Dec 2020 to Nov 2021) averaged 7% more spots per day than year 2 of SC24.
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 northern and southern lights caused by CMEs.
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 ...

The longest total solar eclipse of the century. [57] Lasting 7 min 29 s, it is very close to the theoretical maximum, [58] and is predicted to be the longest eclipse between 4000 BC and AD 6000 (eclipse predictions by Fred Espenak, NASA/GSFC.DEPP).

The Nigeria Renewable Energy Master Plan (REMP) is a policy being implemented by Nigeria's Federal Ministry of Environment that aims to increase the contribution of renewable energy to account for 10% of Nigerian total energy consumption by 2025. [1] The Renewable Energy Masterplan for Nigeria was produced in 2006 with support from the UNDP.
