When was the last solar minimum?
This is called a "Grand Solar Minimum," and the last time this happened, it coincided with a period called the "Little Ice Age" (a period of extremely low solar activity from approximately AD 1650 to 1715 in the Northern Hemisphere, when a combination of cooling from volcanic aerosols and low solar activity produced lower surface temperatures).
When is the next solar maximum?
The latest forecast says that solar maximum—when the number of sunspots peaks and our star is at its most active—will occur between November 2024 and March 2026, but most likely around July 2025. It now looks more like November 2024.

July 2025Not surprisingly, solar maximum is predicted to occur midway through Solar Cycle 25, so between November 2024 and March 2026—and most likely July 2025.
What years were solar maximums?
There was a solar maximum in 2000. In 2006, NASA initially expected a solar maximum in 2010 or 2011, and thought that it could be the strongest since 1958. However, the solar maximum was not declared to have occurred until 2014, and even then was ranked among the weakest on record.
When was the last solar minimum?
The Solar Cycle 25 Prediction Panel, an international group of experts co-sponsored by NASA and NOAA, announced that solar minimum occurred in December 2019, marking the start of a new solar cycle.
How often does the solar maximum occur?
Every 11 yearsEvery 11 years the Sun's magnetic cycle ramps up into overdrive. At the height of this cycle, known as solar maximum, the Sun's magnetic poles flip.
Are we at solar maximum?
The current solar cycle, number 25, started in 2019, which means that the Sun has been slowly ramping up its sunspot and flare activity for the past few years. Solar maximum, when the Sun's magnetic polarity flips and it's expected to be the most active, is anticipated to happen sometime between 2023 and 2026.
What happens after 20 years of solar panels?
The median solar panel degradation rate is about 0.5%, which simply means that a solar panel's energy production will decrease at a rate of 0.5% per year. After 20 years, your panels should still be working at about 90% of its original output.
Was 2014 a solar maximum?
Solar maximum occurred in April 2014 with sunspots peaking at 114 for the solar cycle, well below average, which is 179. Solar Cycle 24's progression was unusual. The Sun's Northern Hemisphere led the sunspot cycle, peaking over two years ahead of the Southern Hemisphere sunspot peak.

What happens when the Sun reaches solar maximum?
The middle of the solar cycle is the solar maximum, or when the Sun has the most sunspots. As the cycle ends, it fades back to the solar minimum and then a new cycle begins. Giant eruptions on the Sun, such as solar flares and coronal mass ejections, also increase during the solar cycle.
What is the largest solar flare ever recorded?
the Carrington EventIn 1859, British astronomer Richard Carrington saw a blast of white light on the surface of the sun. This was the Carrington Event, as scientists now call it, and it is the largest recorded solar storm ever recorded.
Is the Sun getting weaker?
Scientists believe the Sun was at its weakest in 2019 in the last 100 years or so — known as the solar minimum — and 2020 marks the beginning of the 25th cycle. But the odd thing is that solar activity, measured by the number of Sun spots at any given time, is pretty low even in 2020.
What occurs 11 years after a solar maximum?
The Short Answer: The Sun's magnetic field goes through a cycle, called the solar cycle. Every 11 years or so, the Sun's magnetic field completely flips. This means that the Sun's north and south poles switch places. Then it takes about another 11 years for the Sun's north and south poles to flip back again.

Jump to navigation Jump to search. The following is a list of solar cycles (sometimes called sunspot cycles), tracked since 1755 following the original numbering proposed by Rudolf Wolf in the mid-19th century.
When did Sunspot count exist?
Sunspot counts exist since 1610 but the cycle numbering is not well defined during the Maunder minimum. It was proposed that one cycle might have been lost in the late 18th century, but this still remains not fully confirmed. The smoothing is done using the traditional SIDC smoothing algorithm.

How many solar cycles are there?
Scientists recently published a new way to survey the solar cycle: Instead of the traditional linear view of time, they used a mathematical technique to map the last 18 solar cycles onto a circle. What emerged was a more orderly pattern of behavior than expected from the Sun.
How many hours are in a solar clock?
Their so-called solar clock is like a typical clock, where each roughly 11-year cycle can be described over 12 hours. Instead of the time of day, certain “times” correspond to high solar activity. Right now, the scientists say, it’s about 3 o’clock, near the first uptick in activity that comes at the beginning of each solar cycle. The scientists reported their findings in Geophysical Research Letters .
What are the effects of solar cycles?
Solar cycle predictions give a rough idea of what we can expect in terms of space weather, the conditions in space that change much like weather on Earth. Outbursts from the Sun can lead to a range of effects, from ethereal aurora to satellite orbital decay, and disruptions to radio communications or the power grid.
What is the magnetic field at the Sun's poles?
This uses measurements of the magnetic field at the Sun’s north and south poles. The idea is that the magnetic field at the Sun’s poles acts like a seed for the next cycle. If it’s strong during solar minimum, the next solar cycle will be strong; if it’s diminished, the next cycle should be too.
How to model the Sun?
There are many approaches to modeling the Sun in order to develop solar cycle predictions. Some models use ground-based observations spanning hundreds of years; others may use satellite data, which has only been available for the past four decades or so. In recent years, some researchers have incorporated machine-learning tactics. Models may focus on different precursors scientists have identified are linked to solar activity: Earth’s magnetic field, which responds to the Sun’s, and the strength of the magnetic field at the Sun’s poles are most common.
What is the polar magnetic field model?
In recent years, one seems to be especially successful: the polar magnetic field model. This uses measurements of the magnetic field at the Sun’s north and south poles.
When will the Sun's poles peak?
Solar Cycle 24 was a feeble cycle, peaking at 114 sunspots (the average is 179). Solar Cycle 25 is now underway and expected to peak with 115 sunspots in July 2025.

Summary of What Is Solar Maximum and Why Should I Care?
Solar maximum is the point in the sun’s 11-year solar cycle when it is most active.
How many days did the sun not shine in February 2006?
Actually, we're at the beginning of the minimum. February 2006 was the first month in almost ten years with mostly no sunspots. For 21 of February's 28 days, the sun was blank. Hathaway expects this situation to continue for the rest of 2006.
Why is the solar minimum quiet?
Sunspots are in a state of non-stop upheaval. Tangled lines of magnetism twist and stretch until the tension becomes too great and an explosion occurs--a flare. This link between flares and spots is why solar minimum is so quiet.
What does it mean when there are no sunspots?
No sunspots means low solar activity. Sunspots are sources of solar flares and coronal mass ejections that can disrupt radio communications and even cause power outages on Earth during severe magnetic storms. These problems should subside during the year ahead. Auroras, a beautiful side-effect of magnetic storms, should subside, too. "Too bad," says Hathaway, who enjoys Northern Lights.
What is the sunspot cycle?
NASA solar physicist David Hathaway explains: "Solar minimum has arrived.". Sunspots come and go with an 11-year rhythm called the sunspot cycle. At the cycle's peak, solar maximum, the sun is continually peppered with spots, some as big as the planet Jupiter.
When did the sunspot procedure work?
This procedure worked fine in 1610. But in 2006, "we had a problem," says young Jonathan Garcia. "No sunspots," explains his science fair partner Dakota Winkler.
When was Galileo's sketch of the Sun made?
Right: A sketch of the sun made by Galileo in June 1613. [ More]
What did Galileo see in 1610?
The spots themselves did not surprise him. Chinese astronomers looking at the sun naked-eye through clouds and mist had reported seeing sunspots as early as 28 BC. The reality of sunspots was uncontroversial, but the nature of sunspots was a mystery. Were they satellites of the sun? Dark clouds in the sun's atmosphere? Or something else? Galileo's daily sketches showed plainly that the sun was spinning and that sunspots were close to the surface of the spinning orb. Personally, Galileo thought sunspots might be clouds.
