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
The 11-year activity cycle of the Sun is tied to the number of sunspots, which in turn are linked to the intensity of space weather, including solar flare activity from the star.
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).
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 ...
The Sun has reached a period of peak activity in an 11-year cycle known as the Solar Maximum, ... In August, NOAA's Space Weather Prediction Center counted 337 sunspots on Aug. 8.
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 ...
A prediction for Sunspot Cycle 24 (2008-2020) gives a smoothed sunspot number maximum of about 66 in the Summer of 2013. Current observations make this the smallest sunspot cycle since records began in the 1750s. [1] Solar maximum is the regular period of greatest solar activity during the Sun's 11-year solar cycle.
Northern lights activity to increase during solar maximum. Electromagnetic activity is increasing as the sun continues to reach the height of its 11-year solar cycle, which NASA said is expected ...
