Aurora enthusiasts can look forward to an exhilarating natural light show as a solar storm is expected to reach Earth this Thanksgiving, enhancing visibility of the breathtaking northern lights, also known as the aurora borealis. According to the National Oceanic and Atmospheric Administration (NOAA), the auroras will be observable in several northern states in the U.S. on both Thanksgiving and Black Friday.
This spectacular phenomenon is a result of a coronal mass ejection, a powerful burst of solar wind and magnetic fields rising above the solar corona or being released into space. NOAA’s Space Weather Prediction Center has issued a geomagnetic storm watch for Thursday and Friday due to this activity. While the solar storm poses a minor risk to satellites and power grids, it also promises an enchanting display in the night sky for those interested in witnessing this natural wonder.
The northern lights are typically best observed around the magnetic poles; however, this solar storm will push the visibility range further south than usual. States such as New York, Idaho, and other northern and upper Midwest states may enjoy the colorful display. Specifically, cities like Boise, Cheyenne, and Indianapolis could see the auroras shining low on the horizon, depending on local weather conditions.
For those hoping to catch a glimpse of the auroras, NOAA suggests that the best viewing time tends to be an hour or two after midnight, provided the skies are clear. Skimmers should aim for dark locations free from light pollution for the clearest views.
The science behind the northern lights stems from charged particles emitted by the sun. When these particles collide with atmospheric gases like nitrogen and oxygen, they excite the gases and produce light, manifesting as stunning displays characterized by varying colors, depending on atmospheric conditions.
As the sun approaches its solar maximum in its 11-year cycle, an uptick in solar activity is expected, leading to more frequent occurrences of auroras, thus providing additional chances for skywatchers to enjoy this mesmerizing phenomenon. With conditions favorable for more aurora sightings likely to persist until 2025, the upcoming days may be just the start of a season filled with awe-inspiring experiences for aurora chasers.
In summary, with the forecasted solar storm coinciding with the holiday weekend, many across the Northern Hemisphere will have a unique opportunity to enjoy a beautiful natural spectacle as they celebrate with family and friends. Let’s embrace the magic of these northern lights and cherish these moments of wonder in the skies.
