What Washington needs
The aurora reaches the northern edge of Washington at about Kp 5.9, and Seattle at about Kp 6.7. Kp is NOAA's 0-9 index of geomagnetic activity; the higher it goes, the farther south the aurora can be seen.
How to see it
- Get away from city lights and face north, with a clear view of the horizon.
- The best hours are usually 10 pm to 2 am, and clouds hide everything, so check the sky too.
- A phone camera on a long exposure often shows color the eye misses.
