On the heels of a spectacular lunar eclipse earlier this week, the northern lights, or aurora borealis, may grace the skies over parts of the northern United States this weekend. As forecasted by the National Oceanic and Atmospheric Administration (NOAA), a geomagnetic storm is expected to occur, potentially extending the reach of these dazzling lights even as far south as states such as New York and Pennsylvania.

The celestial display is anticipated to commence after darkness falls on the evening of Friday, 28 August, and could linger into the early hours of Saturday, 29 August. Forecasters suggest that a high-speed stream of solar wind, alongside solar material from recent coronal mass ejections (CMEs), may disrupt Earth’s magnetic field sufficiently to produce a G2-level geomagnetic storm, characterised as moderate in intensity.
The science behind the northern lights is intriguing. These captivating light displays are the result of charged particles from the sun colliding with gases in the Earth’s atmosphere, which in turn creates vibrant waves of colour in the night sky. However, the visibility of the auroras is contingent upon various elements, including the intensity of the storm and the observer’s geographic location.
While aurora forecasts can be notoriously unpredictable, the presence of the bright Sturgeon Moon may eclipse the subtler aspects of the auroral displays. Nonetheless, stargazers remain hopeful for an exciting spectacle in the sky.
Optimally, those hoping to witness the northern lights should position themselves outdoors once total darkness sets in, continuing to monitor the conditions throughout the night. Although the exact peak viewing time cannot be predetermined due to the nature of solar activity, enthusiasts are encouraged to remain vigilant as the hours progress.
In terms of geography, the most favourable locations for viewing the auroras include areas in Alaska and remote regions across several northern states. This encompasses Washington, Idaho, Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, Maine, Vermont, and New Hampshire. Should the geomagnetic storm escalate to a G2 level, there is potential for sightings in lower states, including reports of previous visibility in New York, along with Oregon, Wyoming, Nebraska, Iowa, Illinois, Indiana, Ohio, Colorado, and Pennsylvania.
For those situated beyond the main auroral zone, smartphones equipped with night mode capabilities may still capture glimpses of the lights, even if faint. This technological advantage could enhance the experience for individuals based in areas where the northern lights remain obscured from direct view.
To optimise the viewing experience, it is advisable to escape the bright lights of urban areas. Auroras are often quite faint to the naked eye during less intense storms, making darker skies considerably more conducive to visibility. Patience is also essential as the activity can vary rapidly, transitioning from a mere glow to vibrant ribbons of light in an instant.
Those interested in capturing the spectacle through photography can utilise their smartphone cameras to great effect. Interestingly, a smartphone’s camera may outperform the naked eye in detecting auroras, particularly during weaker storms. When attempting to take photographs, users should switch to the night mode or long exposure setting, ensuring to keep the camera steady—utilising a tripod where possible—to facilitate optimal image capture.
For optimal results, participants should explore their device’s settings to engage the “night mode” or “pro mode,” which are designed to extend exposure times and enhance light capture. In a few simple steps, eager photographers can document this cosmic event for posterity, creating memories beneath the shimmering night sky.
As this weekend draws closer, many will be looking up in anticipation. The northern lights represent not only a stunning natural phenomenon but also an opportunity for observation and connection with the universe, instilling a sense of wonder and community among skywatchers seeking to share in the joy of one of nature’s grand displays.
