NASA space weather observations, extremely low sunspot counts, and a severe Polar Vortex are consistent with cyclical global cooling onset. The peak of sunspot activity is known as solar maximum and the lull is known as solar minimum.
At the height of each magnetic flip, the sun goes through periods of more solar activity, during which there are more sunspots, and more eruptive events such as solar flares and coronal mass ejections, or CMEs. The middle of the solar cycle is the solar maximum, or when the Sun has the most sunspots.
Sunspots come and go with an 11-year rhythm called the sunspot cycle.
As the cycle ends, it fades back to the solar minimum and then a new cycle begins.
NASA solar physicist David Hathaway explains: "Solar minimum has arrived."
Hathaway's new email address is … NASA space weather observations, extremely low sunspot counts, and a severe Polar Vortex are consistent with cyclical global cooling onset.
The middle of the solar cycle is the solar maximum, or when the Sun has the most sunspots. But every so often, the Sun becomes quieter, experiencing much fewer sunspots and giving off less energy. “It could happen in a matter of months,” says Martin Mlynczak of NASA’s Langley Research Center. Lack of sunspots could bring a 'Space Age record' for cold temperatures above Earth in a matter of months, NASA scientist warns. At the cycle's peak, solar maximum, the sun is continually peppered with spots, some as big as the planet Jupiter. … Images of the Sun during one solar cycle.
Sunspots come and go with an 11-year rhythm called the sunspot cycle. It is shown here in the 131 Angstrom wavelength, a wavelength particularly good for seeing solar flares and a wavelength that is typically colorized in teal.

But every so often, the Sun becomes quieter, experiencing much fewer sunspots and giving off less energy. Solar Cycle Prediction (Updated 2017/03/23) Please note:Dr. David Hathaway, a member of the MSFC solar physics group for 29 years, transferred (7/9/2014) to NASA's Ames Research Center in California, where he retired in December, 2016.Dr. In both plots, the black line represents the monthly averaged data and the purple line represents a 13-month weighted, smoothed version of the monthly averaged data. Sunspots can change continuously and may last for only a few hours to days; or even months for the more intense groups. Solar maximum occurred during 2001 while 1996 and 2006 were near solar minimum. Solar Activity The Sun is not just a big bright ball. Sunspots have been absent for most of this year, Nasa …
As the cycle ends, it fades back to the solar minimum and then a new cycle begins. Image credit: NASA The magnetic field sometimes changes explosively, spitting out clouds of plasma and energetic particles into space and sometimes even towards Earth.
Sunspots have been absent for most of 2018 and Earth’s upper atmosphere is ... Read more Lack of sunspots to bring record cold, warns NASA scientist The observed and predicted Solar Cycle solar cycle is depicted in Sunspot Number in the top graph and observed and predicted F10.7cm Radio Flux in the bottom graph. _____ “The sun is entering one of the deepest Solar Minima of the Space Age,” wrote Dr Tony Phillips just six weeks ago, on 27 Sep 2018.
The point in time with the most sunspots is called solar maximum. It has a complicated and changing magnetic field, which forms things like sunspots and active regions.
