The sighting of the Northern Lights in northern Colorado two weeks ago may be a mere glimpse of what’s in store in the coming months, judging by “space weather” predictions generated in Boulder that anticipate increasing solar storm activity through 2024.
The magnetic field of the sun reverses polarity every 11 years, meaning its magnetic north and south poles flip. Sun spots, solar flares, and the Coronal Mass Ejections (CMEs) that cause the Northern Lights reach peak levels midway through the cycle, which is predicted to occur in late 2024 or early 2025.
That means the likelihood of more opportunities to see the Northern Lights, also known as the aurora borealis, is strong. They occur when the charged particles ejected by the sun are deflected to earth’s north and south magnetic poles, creating colorful lights when they interact with earth’s atmosphere. The Southern Lights, seen in the southern hemisphere, are called the aurora australis.
