Juneau, Alaska residents were treated to a display of the aurora borealis on the evening of February 15, 2026, with reports of “dim lights” visible despite cloudy conditions. The activity comes as forecasts predict increased geomagnetic activity in the coming days, potentially offering further opportunities to view the northern lights across the state.
Reports surfaced on social media indicating that whereas the aurora was visible in Juneau, cloud cover partially obscured the display. Kyle Ekstrand, posting in the Northern Lights Alert Facebook group, described the lights as “dim” at the skater’s cabin around 1:34 GMT-8. This observation aligns with current conditions, as the aurora visibility in Juneau is currently rated as “Unlikely” according to AuroraMe, with a Kp index of 2.7, which requires a Kp of 4 or higher for optimal viewing.
Aurora Forecast for Alaska
The Geophysical Institute at the University of Alaska Fairbanks is forecasting active aurora activity for February 16, 2026, with a predicted Kp index of 5. In other words that, if skies are clear, active auroral displays may be visible overhead from Utqiaġvik to Anchorage and Juneau, and potentially low on the horizon from King Salmon and Ketchikan. The Kp index measures global geomagnetic disturbance on a scale of 0 to 9, with higher numbers indicating stronger auroral activity. A Kp of 5 suggests a moderate geomagnetic storm.
Looking ahead, the forecast indicates a decreasing trend in geomagnetic activity. The Kp index is predicted to be 4 on February 17, then 3 for both February 18 and 19, before dropping to 2 for February 20-22. Activity is expected to increase again on February 24 and 25, with Kp indices of 5 predicted for both nights. The Space Weather Prediction Center’s Aurora Viewline provides a prediction of the intensity and location of the aurora borealis, showing the southernmost locations from which the aurora may be visible on the northern horizon.
Understanding Aurora Visibility
Several factors influence the visibility of the aurora borealis. The aurora zone, which represents the latitude where auroras are most frequently seen, plays a significant role. Juneau’s magnetic latitude of 61.6° is considered “Good” for aurora visibility, meaning regular storms can produce visible displays. Cloud cover is another critical factor, with clear skies being essential for optimal viewing. Finally, moonlight can wash out fainter auroras, making fresh moon phases the most favorable for observation.
According to AuroraMe, a Kp index of 2.7 is considered “Low” activity. The site notes that a Kp of 4 or higher is needed for aurora visibility in Juneau. The current cloud cover in Juneau is overcast, significantly blocking the aurora.
What to expect in the coming days will depend on both the predicted geomagnetic activity and local weather conditions. While the forecast suggests increased activity on February 16 and 24-25, clear skies will be crucial for viewing the aurora. Residents are encouraged to monitor the aurora forecasts and check local weather reports for the best opportunities to witness this natural phenomenon.
As geomagnetic conditions continue to fluctuate, staying informed about the latest forecasts will be key for those hoping to catch a glimpse of the northern lights. Share your aurora photos and observations in the comments below!
