This phenomenon is expected to lead to more frequent and vivid aurora displays in the night sky. Auroras, commonly known as the Northern and Southern Lights, are natural light displays predominantly seen in high-latitude regions around the Arctic and Antarctic.They are caused by the interaction of solar wind with the Earth’s magnetosphere. In a teleconference with reporters on Tuesday, representatives from NASA, the National Oceanic and Atmospheric Administration (NOAA), and the international Solar Cycle Prediction Panel announced that the Sun has reached its solar maximum period, which could continue for the next year. The solar cycle is a natural cycle the Sun goes through as it transitions between low and high magnetic activity.Roughly every 11 years, at the height of the solar cycle, the Sun’s magnetic poles flip, and the Sun transitions from being calm to an active and stormy state. NASA and NOAA track sunspots to determine and predict the progress of the solar cycle and ultimately solar activity. Sunspots are cooler regions on the Sun caused by a concentration of magnetic field lines and are the visible component of active regions.“During solar maximum, the number of sunspots, and therefore, the amount of solar activity, increases,” said Jamie Favors, Director of the Space Weather Program at NASA Headquarters in Washington. “This increase in activity provides an exciting opportunity to learn about our closest star — but also causes real effects at Earth and throughout our solar system.”Solar activity strongly influences conditions in space known as space weather. This can affect satellites and astronauts in space, as well as communications and navigation systems, such as radio and GPS, and power grids on Earth.From May 3 to May 9, 2024, NASA’s Solar Dynamics Observatory observed 82 notable solar flares.<h2>Solar maximum boosts aurora displays</h2>The flares came mainly from two active regions on the Sun called AR 13663 and AR 13664.This period included nine X-class solar flares, the most intense type of solar flare. “This announcement doesn’t mean that this is the peak of solar activity we’ll see this solar cycle,” said Elsayed Talaat, Director of Space Weather Operations at NOAA. “While the Sun has reached the solar maximum period, the month that solar activity peaks on the Sun will not be identified for months or years.”The peak of the solar maximum period can only be determined after scientists have tracked a consistent decline in solar activity.They predict that the maximum phase will last another year before the Sun enters the declining phase, leading back to solar minimum. NOAA anticipates additional solar and geomagnetic storms during the current solar maximum period, potentially leading to more auroras and technology impacts. Significant storms can also occur during the declining phase of the solar cycle.NASA and NOAA are preparing for the future of space weather research and prediction. In December 2024, NASA’s Parker Solar Probe will make its closest-ever approach to the Sun, beating its own record. This will be the first of three planned approaches at this distance, helping researchers to understand space weather at the source.NASA is launching several missions over the next year to help better understand space weather and its impacts. Space weather predictions are critical for supporting the spacecraft and astronauts of NASA’s Artemis campaign. Surveying this space environment is vital for understanding and mitigating astronaut exposure to space radiation.</div></body>

Solar maximum leads to more auroras: NASA

The Sun has reached its solar maximum, a period of heightened solar activity that increases the likelihood of solar and geomagnetic storms. This phenomenon is expected to lead to more frequent and vivid aurora displays in the night sky. Auroras, commonly known as the Northern and Southern Lights, are natural light displays predominantly seen in high-latitude regions around the Arctic and Antarctic.
