The start of solar cycle 25 was declared by SIDC on September 15, 2020 as being in December 2019. [9] This makes cycle 24 the only "11-year solar cycle" to have lasted precisely 11 years. Details of cycles 1 to 25
‘Significant change’ in Sun’s activity may come as good news for sky watchers ahead of next year’s solar eclipse
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 ...
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).
NASA says the sun is at its maximum and likely to belch out big eruptions that cause technology issues and spark stunning auroras in the next year. The sun is at its 11-year maximum.
Because the solar EUV cannot be monitored from the ground, the joint NASA-ESA Solar and Heliospheric Observatory (SOHO) spacecraft was launched and has provided solar EUV images beginning in 1995. SOHO is a main source of near-real time solar data for both research and space weather prediction and inspired the STEREO mission.
In 2000, Lassen and Thejll updated their 1991 research and concluded that while the solar cycle accounted for about half the temperature rise since 1900, it failed to explain a rise of 0.4 °C since 1980. [78] Benestad's 2005 review [79] found that the solar cycle did not follow Earth's global mean surface temperature.
Shawn Dahl, a forecast coordinator with the Space Weather Prediction Center, told CBS Boston that the northern lights have been so intense lately because of where the sun is in its 11-year solar ...
