‘Significant change’ in Sun’s activity may come as good news for sky watchers ahead of next year’s solar eclipse
The sun emits the largest solar flare of this 11-year cycle, as imaged by NASA's Solar Dynamics Observatory on October 3. NASA/SDO NASA says the sun is in the highly active "maximum phase" of its ...
This prediction is in line with the current general agreement in the scientific literature, which holds that solar cycle 25 will be weaker than average (i.e. weaker than during the exceptionally strong Modern Maximum). [7] However, observations from 2020 to 2022, the first three years of the cycle, significantly exceed predicted values. [12]
Scientists said the sun is now in its solar maximum, or the peak of its 11-year solar cycle.
A preliminary consensus by a solar cycle 25 Prediction Panel was made in early 2019. [24] The Panel, which was organized by NOAA's Space Weather Prediction Center (SWPC) and NASA, based on the published solar cycle 25 predictions, concluded that solar cycle 25 will be very similar to solar cycle 24. They anticipate that the solar cycle minimum ...
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 ...
A solar storm forecast for Thursday is expected to give skygazers in 17 American states a chance to glimpse the Northern Lights, the colorful sky show that happens when solar wind hits the atmosphere.
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.
