Nasa Solar Weather Forecast
The new approach takes advantage of direct observations of magnetic fields emerging on the surface of the Sun – data which has only existed for the last four solar cycles. Mathematically combining the data from the three sources of Sun observations with the estimates of its interior activity generated a forecast designed to be more reliable than using any of those sources alone.

As the magnetic fields change, so does the amount of activity on the Sun's surface, which means more sunspots start to appear. Getty Images Sunspots which appear as dark patches on the star's surface indicate an increase in activity What are sunspots? Sunspots, are dark spots on the Sun, their numbers help scientists monitor our star's activity. Sunspots appear darker because they're cooler than their surroundings, they are the areas of the Sun where huge explosions of light and energy take place. Most sunspots cover an area about the size of the Earth or even bigger! 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. During the peak activity of the last solar cycle, 120 sunspots were recorded. About 115 sunspots are predicted for the peak of this new cycle and anything over 200 is considered to be above-average for sunspots. "Just because it's a below-average solar cycle, doesn't mean there is no risk of extreme space weather, " said Doug Biesecker, a solar physicist.
On Earth, the planet's natural magnetic fields protect us from the effects of space radiation and solar activity. In space, however, there is no natural barrier against the power of cosmic radiation. The next solar maximum is less dangerous? During a solar maximum, sunspots on the surface of the Sun appear as visible dark blotches. Sunspots mark the areas along the Sun's surface where magnetic fields "thousands of times stronger than the Earth's" converge. Space weather: Sunspots are less frequent during a solar minimum (Image: NASA) Sunspots can last anywhere from a few hours to a few days at a time. NASA said: " Fewer of them at the point of maximum solar activity means fewer dangerous blasts of radiation. " Space weather: Intense radiation from the Sun can hinder Moon-bound NASA missions (Image: GETTY) A similar forecast for the upcoming solar maximum was resented this month by the US Space Weather Prediction Center (SWPC). According to the SWPC, the maximum will strike no earlier than 2023 and no later than 2026.

This last summer, the challenge was to develop an AI model to use SDO images to predict spectral irradiance. The breakthrough has been published in Vol. 5, Issue 10 of Science Advances as "A deep learning virtual instrument for monitoring extreme UV solar spectral irradiance. " It was written by Alexandre Szenicer, David F. Fouhey, Andres Munoz-Jaramillo, Paul J. Wright, Rajat Thomas, Richard Galvez, Meng Jin and Mark C. M. Cheung. It can be accessed here.

When the Sun is in turmoil, dangerous amounts of space radiation hurtle through space and towards Earth. The space radiation can cripple satellite networks, disrupt power grids and even threaten Moon-bound missions. Space weather: NASA has predicted the next solar maximum (Image: NASA) NASA said: " The ability to forecast these kinds of events is increasingly important as NASA prepares to send the first woman and the next man to the Moon under the Artemis program. Research now underway may have found a reliable new method to predict this solar activity. " The Sun's activity rises and falls in an 11-year cycle. The forecast for the next solar cycle says it will be the weakest of the last 200 years. " The maximum of this next cycle – measured in terms of sunspot number, a standard measure of solar activity level – could be 30 to 50 percent lower than the most recent one. " The results show that the next cycle will start in 2020 and reach its maximum in 2025. " Radiation: A real risk? The danger is real – in 1972, NASA said a powerful burst of radiation washed over space right in-between the Apollo 16 and Apollo 17 Moon landing.

Space weather triggered by the activity on the Sun follows an 11-year-long cycle of solar minimums and solar maximums. According to NASA, the Sun is now approaching its next cycle, Solar Cycle 25… And it's going to be the weakest it will experience in 200 years. NASA predicts weakest solar activity in 200 years: and next solar maximum for 2015. Picture via NASA During solar minimums, activity on the Sun's scorching surface drops and sunspots and solar flares are less frequent. On the other hand, when the Sun reaches its point of maximum, hundreds of sunspots can erupt on the Sun and unleash jets of energy at the Earth. The Sun is now approaching its next cycle, Number 25. It's going to be the weakest it will experience in 200 years. The next solar cycle will kick off in 2020, followed by a solar maximum in the year 2025. That's good news for space radiation Being able to accurately forecast the Sun's most active years is critical now that NASA has decided to return astronauts to the Moon.
"The Sun's impact on our daily lives is real and is there, " he said.
