As the northern hemisphere approaches the spring equinox, skywatchers are in for a treat, with increased chances of witnessing the awe-inspiring aurora borealis. The National Oceanic and Atmospheric Administration (NOAA) has forecasted that on the nights of Monday, February 23, and Tuesday, February 24, residents across several U.S. states near the Canadian border may have an opportunity to glimpse these stunning polar lights. The event is expected to take place between 10 p.m. and 2 a.m. local time, coinciding with minor geomagnetic storm activity.

This period promises to be particularly fruitful for aurora enthusiasts due to fast-moving streams of solar wind currently affecting the Earth’s magnetic field. The interaction of these charged particles from the sun with the gases in the Earth’s atmosphere leads to the delightful displays of light known as the northern lights. While the overall solar activity in recent weeks remains subdued, the anticipated minor storm conditions may allow the lights to be seen at latitudes further south than typically expected.
The upcoming celestial event is a result of heightened geomagnetic activity, which is likely to intensify in the run-up to the spring equinox on March 20. This increased likelihood of aurora visibility follows the eruption of numerous significant X-class solar flares from sunspot AR 4366 earlier in the month. According to experts, auroras tend to occur more frequently during this window as the solar influence peaks.
For those eager to witness the northern lights, the best viewing conditions are essential. Potential viewers are advised to find dark locations that are removed from city lights, offering an unobstructed view of the northern horizon. Areas in Alaska, Washington, Idaho, Montana, Wyoming, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, and Maine stand the best chance of experiencing these atmospheric phenomena, provided the skies are clear.
To successfully observe the aurora borealis, it is ideal to keep an eye on the NOAA’s 30-minute aurora forecast, which provides real-time updates on solar wind and magnetic field fluctuations. The colours of the aurora can be more vivid in darker settings, so the further one can be from urban illumination, the better.
Photography enthusiasts hoping to capture the beauty of the auroras need not invest in professional equipment. While advanced cameras can yield impressive results, even a smartphone can effectively photograph the northern lights. Users are encouraged to utilize the “Night Mode” or “Pro Mode” settings on their devices, allowing for longer exposure times that are essential for capturing the intricate details and vibrant colours of the auroras.
If conditions permit, the aurora borealis can continue to appear in the days following the peak viewing window, giving observers multiple chances to enjoy this natural spectacle. The key is to remain vigilant, monitor the weather conditions, and keep looking upward.
In summary, the coming days offer a rare opportunity for those in select areas to witness the magical display of the northern lights. By taking the necessary steps to prepare for viewing—seeking dark locations, checking ahistorical forecasts, and employing effective photography techniques—skywatchers can maximise their chances of enjoying this breathtaking celestial occurrence. Be sure to mark your calendars for February 23 and 24, and prepare to be mesmerised.
