NOAA's aurora viewline forecast for overnight on Friday-Saturday, May 15-16, 2026.
In the wake of last night’s display, the northern lights may be visible this Friday night in northern U.S. states and Canada after forecasters at the National Oceanic and Atmospheric Administration predicted a G1 geomagnetic storm may strike overnight. With a new moon on Saturday, May 16, the sky will be free from moonlight, allowing faint aurora to be seen.
Northern Lights Alert: Coronal Hole
It comes in the wake of a coronal hole — a gap in the sun’s corona, its outer atmosphere — which is causing fast-moving solar wind to escape. That turbulence is directed toward Earth, which could spark a geomagnetic storm as charged particles interact with Earth’s magnetic field. They then accelerate down its magnetic field lines at the north and south poles to create ovals of green and red.
