The current solar cycle 25 has been quite active with frequent solar flares and CMEs, some strong enough to send a billion tons of charged particles toward Earth.The frequency of geomagnetic storms caused by solar storms increases and decreases with the sun’s 11-year cycle of activity. So, during solar maximum, geomagnetic storms occuroften.Geomagnetic storms are not dangerous to our human bodies on Earth’s surface. But they can affect some earthly technologies, such as power grids, communications and satellites in orbit around Earth.Space observatories constantly monitor the sunIn 2024, during Solar Cycle 25, the sun has been active with large sunspots and frequent solar flares. During the active part of the sun’s 11-year cycle of activity, those using telescopes equipped with special solar filters to peer at the sun – or photograph it – can see dark sunspots dotting the sun’s surface. Space observatories will detect short-lived but brilliant and powerful solar flares – intense bursts...
