Unlike the 400-year history of sunspot monitoring, this will be only the third solar maximum for which we have continuous helioseismic coverage, said Sarbani Basu, an astronomer at Yale University in New Haven, Conn. Each granule represents a small convection cell on the solar surface, bringing hot material up to the surface and bringing cooler material back down.

The image covers a patch of the Sun 36,500 × 36,500 kilometers (22,600 × 22,600 miles) in area, and the smallest features are only 30 kilometers (18 miles) in size. Inouye Solar Telescope is the highest-resolution image of the solar surface ever taken. The Sun’s Structural Secrets This first-light image from the Daniel K. “In the last decade, we’ve only observed about 40 large, or X-class, flares.” Low-intensity flares are far more common even in weak solar cycles and at solar minimum, “so even though we’re taking so much data, in some ways we’re data starved because we have a really imbalanced data set,” she said. “We want to understand how flaring activity depends on solar cycle,” said Monica Bobra, a solar scientist at Stanford University in California. What solar maximum ideally will do is produce flares at a wide range of intensities, especially those at the highest intensities, to help scientists develop more accurate models of flare generation. The truth is that the really extreme storms do not care if the sunspot number maximum is weak.” In fact, University of California, Berkeley space scientist Janet Luhmann noted that despite cycle 24’s lackluster sunspot performance, “one of the most extreme events ever observed with modern instruments occurred in July of 2012.

“We have more than 400 years of nearly continual sunspot observations, so it’s invaluable for putting the current conditions on the Sun in a long-term context.” Given the decidedly average forecast for cycle 25, “we aren’t necessarily expecting extreme space weather. “As crude a measurement as it is for quantifying solar activity, sunspot number is nevertheless the thing I most readily keep an eye on,” said Mathew Owens, a space physicist at the University of Reading in the United Kingdom.

Astronomers have been tracking sunspots for centuries. The 11-year solar cycle is also known as the sunspot cycle because active regions on the Sun’s surface often manifest sunspots. Here are 11 discoveries scientists hope to make during the upcoming solar maximum that weren’t possible during the previous one. Since the previous solar maximum, there have been major advances in solar-observing technology, solar and planetary magnetic theory, and computational power. But whether that trend persists or the maximum of cycle 25 is the same as any other, solar scientists will assuredly learn far more than they did 11 years ago. Scientists hope that cycle 25 will continue to provide more excitement than did cycle 24-they want to see spots and flares of all sizes and intensities and many coronal mass ejections (CMEs) that traverse interplanetary space to interact with planets’ magnetic fields. The field of view is 19,312 kilometers (12,000 miles) across.

Inouye Solar Telescope in Hawaii took this image of a sunspot on 28 January 2020 as part of its science verification phase. Initial forecasts of cycle 25 predicted that it would produce activity levels similar to those of the previous cycle, which were slightly below average, but “the current cycle has been more active so far” than during the same phase of cycle 24. “As we are heading towards the solar maximum, we expect many more active regions to appear,” said Kiran Jain, a solar physicist at the National Solar Observatory in Boulder, Colo. Solar maximum, when the Sun’s magnetic polarity flips and it’s expected to be the most active, is anticipated to happen sometime between 20. 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. But the overall pattern remains the same and repeats every 11 years, even if the details vary slightly each time. That’s not to say a solar cycle is exactly the same every time-some cycles are far more active than others, and sometimes the Sun skips a cycle completely. We are in the middle of a solar cycle, and we’ve been here before.
