What is a solar cycle?
solar cycle, period of about 11 years in which fluctuations in the number and size of sunspots and solar prominences are repeated. Sunspot groups have a magnetic field with a north and a south pole, and, in each 11-year rise and fall, the same polarity leads in a given hemisphere while the opposite polarity leads in the other.
How does the solar cycle work?
The solar cycle is driven by the sun's magnetic field, according to NASA Space Place. Every 11 years or so, the sun's magnetic field flips so north becomes south and south becomes north. Changes in the sun's magnetic field affect the amount of activity on the solar surface.
How does the solar cycle affect Earth?
The Sun follows a roughly 11-year rhythm of waking up and becoming very active before calming down again, a stellar beat known as the solar cycle. This affects Earth because it shapes space weather, determining how much radiation, magnetic field and particles the Sun flings out into space and towards our planet. What is the solar cycle?
What is solar cycle 25?
Accessed 15 August . Solar cycle, period of about 11 years in which fluctuations in the number and size of sunspots and solar prominences are repeated. Solar cycle 25 began in and will reach maximum in , but that maximum is predicted to be weak, like that of solar cycle 24.
What is Solar Orbiter's 25th solar cycle?
One of Solar Orbiter’s first discoveries was a phenomenon similar to solar flares called campfires. The sun is now in its 25th solar cycle since astronomers started gathering accurate sunspot data more than 250 years ago. Solar Cycle 25 started in and will continue roughly through .
What happens at the trough of the solar cycle?
At the trough of the solar cycle, sunspots are sparse, and subsequent solar flares and CMEs — which typically originate from sunspot regions — can be absent for months at a time. This phase of the solar cycle is called solar minimum, which is in stark contrast to solar maximum, the peak of the sun's 11-year cycle of activity.
