As August draws to a close, a celestial spectacle is set to captivate stargazers across the northern United States. The month’s full moon, which will cast a striking coppery red hue during a partial lunar eclipse, coincides with increased solar activity that may bring the northern lights, or aurora borealis, to shine in spectacular displays above select areas.

The partial lunar eclipse is expected to reach its peak at 12:13 a.m. ET on Friday, August 28, when a small portion of the moon will remain visible outside of Earth’s shadow. This event marks not just a rare visual delight but also a promising opportunity to observe the auroras illuminated by geomagnetic storms generated by solar particles colliding with the Earth’s atmosphere.
In anticipation of the auroras, the National Oceanic and Atmospheric Administration (NOAA) has issued geomagnetic storm watches from August 27 through August 29. The agency forecasts disturbances that could reach G1 or G2 storm conditions, an indication that conditions are ripe for aurora sightings. Similarly, the UK’s Met Office has reported that strong solar winds and potential coronal mass ejections could enhance the likelihood of these stunning light displays.
For those keen to catch the northern lights, the optimal viewing times are likely to occur late on Thursday, August 27, extending through Friday night. As the solar winds arrive, they may generate favourable conditions that are conducive to auroral activity. However, in keeping with their unpredictable nature, observers are advised to stay updated with NOAA’s real-time aurora forecasts to optimise their viewing experience.
The northern lights are typically most visible in regions closer to the Arctic Circle. Under normal G1 conditions, ideal locations include Alaska and northern states such as Washington, Idaho, Montana, North Dakota, Minnesota, Wisconsin, Michigan, Maine, Vermont, and New Hampshire. In the event of increased intensity, G2 levels may allow faint auroras to be seen in locations further south, potentially reaching areas in Oregon, Wyoming, Nebraska, Iowa, Illinois, Indiana, Ohio, Pennsylvania, and New York. Although not every state on this list will guarantee a view, clear skies and an unobstructed northern horizon significantly enhance the chances of witnessing this breathtaking phenomenon.
To ensure the best experience while watching the northern lights, enthusiasts should seek locations away from the glare of city lights. Ideally, a dark spot with a clear view of the northern sky will offer the most vivid display. Skywatchers should also utilise resources such as NOAA’s aurora forecast and various space-weather apps for up-to-the-minute information on solar wind and magnetic field fluctuations, which can influence the visibility of the auroras.
For those wishing to capture this extraordinary event, photography of the auroras can yield stunning results, even from a smartphone. Modern devices are remarkably sensitive, capable of picking up auroral colours that might be invisible to the naked eye. By adjusting settings to “Night Mode” or “Pro Mode” with extended exposure times, users may find their photographs reveal a vibrant palette of greens, pinks, and purples, transforming what may appear as a simple grey haze into a brilliant representation of the auroras.
In conclusion, this week’s convergence of a partial lunar eclipse and solar activity presents a rare and exciting opportunity for skywatchers across the northern United States. With careful planning and optimal conditions, nature enthusiasts may find themselves mesmerised by the beauty of the aurora borealis dancing across the night sky, making for a truly unforgettable celestial experience. As the realms of astronomy and atmospheric science intertwine, it is moments like these that remind us of the wonders that the cosmos can offer.
