The Northern Lights Could Be Visible Over Parts of the Northern U.S. This Week

You don't need to live north of the Arctic Circle to see the northern lights. On rare occasions, the phenomenon is visible from upper parts of the contiguous U.S. That will be the case this week, when the aurora borealis lights up skies above Maine, Michigan, and other states across the northern border.

As Thrillist reports, the Space Weather Prediction Center has forecast G1 and G2 geomagnetic storms for Sunday, September 27 through Tuesday, September 29. A geomagnetic storm occurs when activity on the sun shoots solar particles toward our planet. At high latitudes, those particles react with gas molecules in the Earth's atmosphere, resulting in waves of green, pink, blue, and purple light undulating in the night sky.

Normally auroras are limited to the poles, because that's where the concentration of magnetic energy is the strongest. It takes an especially potent solar storm to make the spectacle appear farther south, and that's exactly what's been predicted for early this week. The first storm, a G1 or minor level, is set to last from September 27 through the 28th. It will be followed immediately by a G2 or moderate-level solar storm on September 29.

Northern lights from the G1 storm have already been spotted in Minnesota, and the aurora from the G2 storm is expected to extend even lower. States that have a shot at catching the northern lights on Tuesday include Idaho, Iowa, Maine, Michigan, Minnesota, Montana, New Hampshire, New York, North Dakota, South Dakota, Vermont, Washington, and Wisconsin.

If you don't live within the range of September's light show, there will still be plenty of reasons to look up in the coming weeks. Here are some celestial events to look for in October.

Uranus Reaches Opposition on Halloween in 2020

Uranus is roughly 1.75 billion miles away from Earth, which makes it difficult to spot without a telescope most nights. But on Saturday, October 31, the seventh planet from the sun will be worth looking for. Uranus reaches opposition that night, making it appear extra bright in the night sky.

What Is Uranus at Opposition?

An opposition occurs when the Earth falls perfectly between another planet and the sun. When this happens, the sun's light appears to fully illuminate the planet's surface, boosting its brightness level to the maximum.

Uranus reaches opposition on October 31 in 2020. During this event, Uranus will hit a limiting magnitude of 5.86, which is about the minimum brightness for what's visible with the naked eye.

How to Look for Uranus at Opposition

Spotting Uranus at opposition will be slightly more difficult in 2020 than in years past. The phenomenon coincides with a full moon that will make dimmer stars and planets—including Uranus—harder to see in the night sky. The planet sits in the constellation Aries, which regrettably appears close to the moon for most of the night.

Uranus should appear as a small, blue-green disc when using a telescope. Even if you have trouble spotting the seventh planet, it will still be worth checking out the night sky on October 31: Halloween this year coincides with a rare blue moon.
