As the Easter weekend approaches, stargazers may be in for a spectacular treat, as the northern lights, also known as the aurora borealis, are expected to grace the skies. Following a coronal mass ejection (CME) that impacted Earth earlier this week, heightened geomagnetic activity is predicted to result in vivid displays of this natural phenomenon throughout the holiday.

Distinctly caused by interactions between charged solar particles and the gases in Earth’s atmosphere, the auroras create stunning waves of light. While visibility largely depends on geographic location and atmospheric conditions, recent solar events have led to a surge in geomagnetic activity, making this weekend an opportune time for those keen to witness the display.
The National Oceanic and Atmospheric Administration (NOAA) has forecasted conditions that may result in unsettled to minor geomagnetic storms (rated G1), with the possibility of isolated moderate storms (G2) emerging as the solar winds continue to energise the planet’s magnetic field. This recent burst of solar activity has essentially “primed” the magnetosphere, and experts believe that auroral displays could be observed from Thursday night, April 2, and persist through Saturday, April 4, before gradually subsiding.
Viewing opportunities are anticipated to be most favourable from the evening of April 2 into the following day. During this period, observers may get a firsthand look at intensified auroral activity due to the lingering effects of the recent CME coupled with fast solar wind streams. For those living in high-latitude regions—such as Alaska, northern Canada, and parts of Scandinavia—the chances of witnessing the northern lights are particularly promising.
Interestingly, during stronger geomagnetic storms, the auroral oval can extend southward. This means that areas in the northern United States, especially those near the Canadian border, could potentially experience views of the auroras, provided the skies are dark and clear. NOAA emphasises that the farther north one is and the darker the surrounding environment, the better the chances for a stunning display.
When aiming to observe this celestial event, it is imperative to find a location well away from light pollution. Those interested can use light pollution maps or dark-sky finders to locate optimal viewing spots. It also helps to have a clear view of the northern sky and a good measure of patience, as auroras are notoriously unpredictable, often appearing in waves.
For photography enthusiasts hoping to capture the northern lights, clarity and stability are crucial. While professional equipment can enhance the experience, it is not essential. Many smartphones today come equipped with a “Night Mode” or “Pro Mode,” which allows for extended exposure times, making it easier to photograph the auroras without the need for advanced gear.
In the coming days, as various visual and technical preparations are considered, the northern lights are set to add an enchanting aspect to the Easter weekend. With ongoing live forecasts able to provide updates on the evolving geomagnetic conditions, avid observers will have insight into when the best moments to look up might be.
As the days draw nearer to the holiday weekend, enthusiasts of all ages should prepare for what promises to be an awe-inspiring experience. The beauty of the auroras and the wonder of celestial activity remind us of the natural marvels that exist beyond our atmosphere, offering a striking backdrop to the festivities of the season.
