Frequently Asked Questions
Can you see the Northern Lights in Arizona tonight?
Arizona: it depends on where you are and on tonight's sky. Flagstaff needs about Kp 7; Tucson needs about Kp 8. On top of that it takes a clear, dark sky — cloud blocks aurora at any Kp. The table at the top of this page has tonight's forecast city by city.
What Kp index is needed to see the Northern Lights in Arizona?
Arizona has no single number. The higher the Kp, the further from the pole the auroral oval reaches, so the threshold rises with distance from the pole: Flagstaff needs about Kp 7, Tucson about Kp 8. Each city's page gives its own threshold.
What are the best months to see the Northern Lights in Arizona?
The best months to see the Northern Lights in Arizona are typically September to April, when nights are darker and aurora viewing conditions are better.
Where is the best place to see the Northern Lights in Arizona?
