Anchorage

Anchorage, Alaska’s largest city, is in the south-central part of the state on the Cook Inlet. It’s known for its cultural sites, including the Alaska Native Heritage Center, which displays traditional crafts, stages dances and presents replicas of dwellings from the area’s indigenous groups. The city is also a gateway to nearby wilderness areas and mountains including the Chugach, Kenai and Talkeetna

The northern lights can be seen from September to April with the best viewing in winter.

How are my chances of seeing the aurora today?

Many factors contribute to your likelihood of viewing the aurora in Anchorage. Geomagnetic activity, cloud cover and the amount of ambient light all play a big part. Check the forecasts for how good the viewing conditions are today.

Aurora Probability and Atmospheric Conditions

0%

There is a 0% chance of seeing the aurora overhead in the Anchorage area (forecast for 11 April 2026 at 7:58pm UTC)

HPI 21 GW

The Hemispheric Power Index (HPI) is a vital measure used to assess the strength of auroral activity at the poles. It estimates the total auroral energy input, with values above 20 GW indicating an aurora-active state. When the HPI reaches levels of 100 GW or more, it signifies a very significant geomagnetic storm, which can lead to spectacular auroral displays.

Density 2.67 p/cm3

Solar wind density refers to the number of charged particles in a given volume of the solar wind, typically measured in particles per cubic centimetre (p/cm3).

A typical solar wind density is around 2.76 p/cm3.

The density of the solar wind affects how many particles reach the Earth’s magnetosphere. A higher density means more particles are available to interact with the Earth’s magnetic field. When these charged particles collide with the gases in the Earth’s atmosphere, energy is released in the form of light that we see as the aurora.

Speed 595.8 km/s

Solar wind speed refers to the velocity at which charged particles are ejected from the Sun’s outer atmosphere, known as the corona.

A typical solar wind speed is about 375 km/s. When both speed and density are high, the energy transferred to the Earth’s magnetosphere increases, enhancing the chances of seeing vibrant auroras.
