Forecast Overview
NOAA’s Space Weather Prediction Center projects a minor G1 geomagnetic storm for the night of April 25-26, 2026, with a peak Kp index of 4.67. The forecast suggests auroral visibility could extend to as many as 24 U.S. states, from Alaska and Washington to Maine, New York, and Pennsylvania, with optimal viewing between 10 p.m. and 2 a.m. local time.
Solar Activity Context
The display follows a period of heightened solar activity that peaked in 2024-2025, when NASA recorded a 500-year auroral surge. Recent events include double M1-class flares on April 23 and an X2.5 flare near the solar limb, whose coronal mass ejection is expected to graze Earth’s magnetosphere.
Key Data
Key metrics: peak Kp 4.67 (scale 0-9), G1 storm with a small chance of G2, and a projected view line covering up to 24 states; NOAA’s Sunday outlook drops to Kp 3, lowering visibility.
Uncertainties
Forecasts remain provisional; cloud cover, light pollution and local weather can suppress visibility even under a G1 storm, so observers are advised to seek dark, northern sites.
Conflicting Reports
Sources differ: Forbes limits visibility to ten northern states and cites a Kp of 4.67, while Daily Galaxy projects auroras across twenty-four states without a numeric Kp and emphasizes Saturday night only.
Significance
Auroras attract tourism and photography and serve as space-weather indicators that can affect aviation, power grids and satellite operations.
Official Statements
NOAA emphasizes the 4.67 Kp peak and a likely G1 storm, while NASA notes that solar activity is expected to wane later this decade.

- “NOAA recommends traveling further north, finding the highest vantage point possible and avoiding light pollution.” — NOAA
- “Photographers using iPhones should use the night mode camera setting, turn off flash and shoot in the RAW format.” — NOAA
- “The aurora may appear as a faint green glow at first, sometimes mistaken for distant light pollution, before intensifying into more defined arcs or moving curtains.” — NOAA
- “Cloud cover can obscure the display entirely, while clear, dark skies dramatically improve visibility.” — NOAA
- “Isolated G1 (Minor) geomagnetic storming conditions are possible on April 26 in response to the arrival of the glancing CME impact,” said NOAA.
Outlook
NOAA will update Kp forecasts through the weekend and issue alerts for any further CME impacts.
