NOAA Sees Northern Lights Overnight Across Much of Canada and 15 U.S. States

Overview

• Forecasters expect activity late Friday into early Saturday, with the best chance before sunrise on Jan. 17.
• The event is rated G1 with a Kp near 5, with a possibility of brief G2 spikes that could push visibility farther south.
• NOAA’s view line covers much of Canada and parts of roughly 15 U.S. states from Washington to Maine, reaching as far south as Iowa and northern-tier regions.
• The disturbance is linked to a coronal-hole high-speed stream interacting with Earth’s magnetic field following recent solar eruptions.
• Visibility is not guaranteed and depends on clear, dark skies; monitor NOAA’s 30-minute aurora forecast, face north, and note the thin waning crescent moon will minimize glare.
