Flattop Park Trail : Anchorage : Seek The Aurora

Anchorage

Home / 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?

1%

There is a 1% chance of seeing the aurora overhead in the Anchorage area (forecast for 13 June 2025 at 9:50pm UTC)

Kp 5.00

The Kp-index is a scale used to measure geomagnetic activity. It ranges from 0 to 9, with higher values indicating greater geomagnetic activity.

0-2 (Very low) Far north, quite dim, and not very active.
3-5 (Moderate) Can be seen further south, with increased brightness and activity. Chance of good viewing conditions nearer the pole.
6-7 (High) Visible in many northern regions, with vibrant displays.
8-9 (Extreme) Widespread visibility, often seen in areas much further south than usual, with intense and colorful displays.

Bz -9 nT

Bz refers to the north-south orientation of the magnetic field embedded in the solar wind. It is measured in nanoteslas (nT).

When Bz is negative (southward), it allows solar wind particles to penetrate the Earth’s magnetic field more easily. A strong negative Bz is often associated with increased chances of seeing the Northern Lights.

Conversely, when Bz is positive (northward), the Earth’s magnetic field tends to block the solar wind, resulting in reduced auroral activity.

Density 21.24 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 centimeter (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 442.7 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.
