A dazzling celestial display could grace the night skies across sections of the northern United States heading into the weekend. As a robust current of solar wind collides with Earth's magnetic shield, stargazers might catch a glimpse of the northern lights overnight on Friday, October 30, stretching right through to Saturday, October 31, which marks Halloween.

Space weather analysts anticipate a G1-class geomagnetic disturbance, heightening the probability that the aurora borealis will become visible from northern tier states sitting along the Canadian border. Observers who find themselves under the right atmospheric conditions may even be able to capture the glowing lights using a standard smartphone camera.

This cosmic event follows closely on the heels of the recent full Hunter’s Moon. The lunar cycle moves into its last quarter phase on Sunday, November 1—coinciding with Halloween night—with moonrise expected around midnight. Furthermore, the end of Daylight Saving Time across the majority of the U.S. and Canada occurs on that same Sunday.

Adding to the weekend's astronomical lineup is the peak of the Taurid meteor shower. Although it rarely yields a high volume of shooting stars, this particular shower carries a reputation for producing exceptionally bright and striking fireballs.

Will You See the Northern Lights Tonight?

Projections issued by space weather specialists at the National Oceanic and Atmospheric Administration indicate that a G1-class geomagnetic storm could kick off near 8 p.m. EDT on Friday, October 30. Anticipating Kp 5 atmospheric conditions, the activity is slated to persist into Saturday, October 31.

NOAA notes that unsettled to active conditions are expected late on October 30 as coronal hole high-speed stream impacts commence, pushing G1 minor geomagnetic storms into likely territory by October 31. This specific stream consists of a rapid gush of charged particles breaking free from a darkened expanse in the solar atmosphere, frequently traveling at speeds exceeding one million miles per hour. Upon hitting our planet, this solar wind disrupts the geomagnetic field, sparks storms, and occasionally pushes the aurora display further south than typical.

Where Will the Aurora Be Visible?

Should the predicted G1 geomagnetic storm materialize, the glowing phenomenon could emerge from low-light regions within northern U.S. territories bordering Canada. Provided the skies remain unobstructed, potential viewing areas include Alaska alongside portions of Washington, Idaho, Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, Maine, Vermont, and New Hampshire.

The dedicated aurora-tracking platform Cosmik supplies live probability metrics for every state and hundreds of cities across multiple languages, leveraging official NOAA information to help enthusiasts verify local visibility.

How Can You Maximize Your Chances of Seeing the Aurora?

Anyone hoping to witness the aurora should journey away from urban lights to a dark destination offering an unhindered perspective of the northern horizon. Success depends heavily on multiple factors, including solar wind velocity, cloud coverage, ambient light pollution, and the orientation of the interplanetary magnetic field.

This directional component, known as Bz, plays a decisive role. When Bz points southward, it achieves a stronger coupling with Earth's magnetic field, permitting energy and charged particles to flood the magnetosphere. Sustained southern orientation allows the aurora to intensify and expand southward. Conversely, a northward Bz orientation generally results in a muted display restricted to higher latitudes.

Utilizing dedicated software applications such as Aurora Now, My Aurora Forecast, or Glendale Aurora can provide real-time push notifications and up-to-the-minute solar wind metrics to help hunters track the action.
