The Northern Lights

(from Jökull Másson)

Did you know the Northern Lights are occasionally visible from Seattle? We’re at magnetic latitude 52.7, high enough to see some Aurora when the sun is raging.

When the POES activity level hits 9 or 10,

or the estimated planetary Kp gets above 6

and the night sky is clear, we should be able to see the Northern Lights.

In my six years here, all these have come together exactly once.
