Direct answer: Last night’s northern lights were likely visible due to heightened solar activity sending charged particles toward Earth, triggering auroral emissions in high-latitude skies. Specific visibility depended on local weather, light pollution, and clear skies, but many observers across North America reported aurora activity during that period. Context and what drove the display:

• Solar activity: A coronal mass ejection (CME) or high-speed solar wind stream interacted with Earth’s magnetosphere, energizing auroral currents and producing vivid displays in suitable locations. This is the usual driver behind strong aurorae around the time in question. [NOAA-space weather guidance and regional forecasts noted heightened geomagnetic activity tied to recent solar events.]
• Geomagnetic conditions: Disturbances reaching G2–G3 (moderate to strong) levels increase the likelihood of visible auroras at lower latitudes, depending on local viewing conditions. Observers in the northern U.S. and parts of southern Canada often catch sight of the lights under clear, dark skies when such storms occur.
• Timing and location: Auroras are most easily seen after dusk and well into the night, especially from locations with minimal light pollution and an unobstructed northern horizon. Reports during the date range you referenced indicate multiple nights with auroral display across broad swaths of the northern hemisphere.

What you can do to verify for your location:

• Check real-time aurora forecasts from space weather services (they provide short-range alerts and probabilistic visibility maps).
• Look for clear skies, and give your eyes 15–20 minutes to adapt to darkness; the brighter displays can be seen even in areas with some light pollution, while very dark sites yield the most dramatic effects.
• Use camera settings that enhance faint auroras (long exposure, tripod, and moderate ISO) if you’re capturing the scene.

If you’d like, share your approximate location and the exact date you saw the display, and the type of view you had (sky condition, light pollution level, how long the display lasted). I can tailor a more precise visibility assessment and provide the best times to watch for similar activity based on current forecasts.
