The northern lights, also known as the aurora borealis, are set to potentially illuminate parts of the northern United States as we transition from the evening of June 29 into the early hours of June 30. This celestial phenomenon coincides with the appearance of the full Strawberry Moon, which promises to create a stunning visual blend in the night sky.

Observers should prepare for an enchanting night of skywatching, as a burst of solar material is expected to reach Earth, generating ideal conditions for viewing the aurora. The northern lights form as charged particles from the sun interact with the Earth’s atmosphere, leading to captivating waves of light. However, visibility is contingent on a range of factors, including the intensity of the geomagnetic activity and geographical location.
The full Strawberry Moon, named for the strawberry harvesting season in North America, will add a layer of intrigue to this astronomical display. While the brightness of the moon may dilute the visibility of a more subdued aurora, it could simultaneously provide a dramatic backdrop for those fortunate enough to witness both phenomena.
This potential aurora is a consequence of a coronal mass ejection (CME) that left the sun on June 26. According to the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Prediction Center, these massive clouds of plasma can disturb the Earth’s magnetic field upon arrival, occasionally allowing for sightings of the aurora at lower latitudes than typically expected. Although this occurrence is not predicted to escalate into a significant northern lights event, it could reach levels of G1 or G2, corresponding to minor to moderate geomagnetic storms. Such conditions might yield a faint glow on the northern horizon for skywatchers situated close to the U.S.-Canadian border.
For those interested in catching a glimpse of the aurora, the ideal window for viewing is projected to take place overnight from June 29 to June 30. However, predictions regarding the timing of CME arrivals can be imprecise. Therefore, the aurora might appear earlier or later than initially suggested. Experts from NOAA have advised that enhanced conditions are likely to manifest early to mid-morning on June 30, following the CME. Delightedly, once the CME reaches satellites positioned before Earth, observers may receive timely updates, sometimes only 30 to 60 minutes prior to a potential increase in auroral activity.
Regions that stand the best chance of witnessing this spectacular light show include northern states adjacent to Canada, such as Washington, Idaho, Montana, North Dakota, South Dakota, and Minnesota. Additionally, areas like Wisconsin, Michigan, and Maine are also in prime position. Should the storm strength prove favourable, more southern states—including Oregon, Wyoming, Nebraska, Iowa, Illinois, Indiana, Ohio, New York, Vermont, and New Hampshire—may also catch a glimpse of the northern lights.
To maximise viewing opportunities, it is advisable to seek out locations with minimal light pollution. Dark, open spaces or elevated positions provide the best vantage points, as urban areas typically hinder visibility due to streetlights and buildings. Observers should also allow their eyes to adjust to darkness for at least 20 minutes and limit the use of bright screens during this adjustment period. Apps and real-time monitoring tools such as Space Weather Live and My Aurora Forecast can aid in tracking auroral developments.
For those keen to document the fleeting beauty of the northern lights, capturing these awe-inspiring displays doesn’t necessitate high-end equipment. While professional gear can enhance the experience, smartphones equipped with night or pro modes are sufficient for photography. A steady setup is essential for long exposure shots, which effectively capture the dynamic movements of the auroras.
As the night unfolds on June 29, both the full Strawberry Moon and the northern lights will invite skywatchers to look upward. It is an extraordinary opportunity to appreciate two celestial events that promise to create stunning imagery above. Whether the aurora steals the show or the moon shines brighter, the night sky is set to deliver a memorable spectacle for those willing to observe.
