Summary
This month, those interested in seeing the northern lights, or auroras, may have the best chance until 2030, due to a combination of the March equinox and high solar activity. The Earth’s position during the March equinox and the peak of the solar cycle increases the likelihood of auroral displays.
Key Facts
- The March equinox occurs on March 20 and marks the start of astronomical spring.
- During the equinox, Earth's axis is side-on to the sun, shortening nights in the Northern Hemisphere.
- The "equinox effect" increases the likelihood of northern lights around March and September.
- Northern lights happen when electrons collide with Earth’s atmosphere, creating auroral ovals at magnetic poles.
- Solar maximum, the peak of the sun's activity cycle, increases space weather events and northern light visibility.
- The current conditions could lead to the best northern lights displays until the mid-2030s.
- The next solar cycle, Solar Cycle 26, is expected to begin between January 2029 and December 2032.
- According to NASA, March and September are statistically the best months to see auroras.
