Solar storms are expected to produce vibrant northern lights across many regions of Canada and northern U.S. states for a consecutive night. The U.S. National Oceanic and Atmospheric Administration (NOAA) forecasts that the spectacle will be visible in various Canadian provinces and territories, including B.C., Alberta, Saskatchewan, Manitoba, Yukon, Northwest Territories, Nunavut, Labrador, and the northern parts of Ontario and Quebec. Shawn Dahl from the Space Weather Prediction Center anticipates the dazzling show to last through the night, reaching its peak intensity between 7 and 10 p.m. ET. It is advised for those interested in viewing the display to stay updated with local weather forecasts.
Recent solar activity has resulted in powerful solar flares on the sun, followed by coronal mass ejections (CME) – rapid particle explosions traveling through the solar wind. Two Earth-directed CMEs arrived on Tuesday night, extending the reach of the lights, commonly known as the aurora borealis, as far south as New Mexico and Texas.
The Space Weather Prediction Center (SPWC) suggests that the geomagnetic storm, which began Tuesday night, may continue into Wednesday and possibly Thursday, albeit with reduced intensity. Astronomers and space weather experts have been surprised by the visibility of northern lights in unexpected locations recently, attributed to the sun’s current heightened activity cycle.
Dr. Jesse Rogerson, a Canadian astrophysicist, explains that the phenomenon of northern lights occurs when solar particles interact with the Earth’s magnetic field, creating a luminous display as they collide with the atmosphere. The best viewing locations are areas with clear skies, away from city lights to minimize light pollution. The sun’s peak activity phase every 11 years contributes to the increased occurrence of these colorful displays.
The rare sightings of northern lights in various regions highlight the ongoing solar activity and the potential for more auroras in the near future. Solar storms not only bring visual delights but can also disrupt Earth’s systems, including the power grid and satellite communications. Historical events such as the 1859 solar storm causing auroras in Hawaii and the 1972 storm potentially detonating U.S. sea mines emphasize the impact of such phenomena on Earth.
Aurora enthusiasts are encouraged to check NOAA’s Space Weather Prediction Center or aurora forecasting apps for updates on northern lights forecasts. Optimal viewing conditions involve quiet, dark locations away from urban lights, preferably in national parks. It is also recommended to monitor weather conditions to ensure clear skies for the best aurora viewing experience. Taking photos with smartphones can capture details of the aurora not visible to the naked eye.
