Northern Lights

The northern lights can be incredibly bright, multihued and fast moving. The most common color is a brilliant yellow-green. Colorful northern lights displays can produce red, blue and purple patterns.
Glowing, dancing curtains of light that ripple and sway, fold and unfold then suddenly disappear, only to reform in a new shape minutes later.
Anchorage's bright starry nights are nature’s perfect backdrop for dancing northern lights, also known as Aurora Borealis. Fall, winter and spring are the prime seasons for viewing the northern lights, and the best displays tend to be accompanied by sub-zero temperatures and moonless skies. The best hours are often near midnight,  Local Aurora Forecasts are available online or in the weather section of the Anchorage Daily News.
Many of the area hotels have a “northern lights wake up call” for guests who indicate that they want to be awakened if the lights are dancing in the night sky.
