• March 2026 might be the greatest opportunity to witness the Northern Lights before the 2030s because of solar timing and the equinox effect.
• The Russell-McPherron effect around the March equinox causes aurora activity to surge, boosting the likelihood of brighter auroras.
• Before the next solar maximum in 2035–36, this equinox might be one of the last best viewing windows as the Sun enters a quieter period.
