Seeing the Aurora in Juneau
Found in Alaska, Juneau offers unique opportunities for aurora hunters visiting United States. Because it sits at 58.3°, seeing the aurora borealis here requires a fairly strong geomagnetic storm. Keep a close eye on space weather forecasts and be ready to travel to darker skies if a severe storm hits.
Aurora Season in Juneau
While auroras are driven by solar storms rather than seasons, you still need dark skies. In Juneau, your best chances are during the darker months from October through February.
FAQ
What Kp index do I need to see the northern lights in Juneau?
In Juneau, you usually need at least Kp 3 to have a reasonable chance of seeing the northern lights. Lower Kp can still bring a faint aurora display low on the northern horizon, but it is less common.
This is based on magnetic latitude, and Kp index is a global geomagnetic index, so treat it as a rule of thumb, not a location-specific guarantee.
Tonight, the NOAA Kp index forecast is 2 to 2.7. That is a bit below the usual Kp index threshold for Juneau, so there is still a small chance of seeing faint aurora low on the northern horizon.
