During the winter months the Aurora Borealis, a manifestation of solar particles colliding with the Earth’s magnetic field, occasionally reaches the lower latitude of the United Kingdom. Observers recorded the phenomenon on 15 February 2024 over the southern Lake region, noting that the brightest emission consisted of a primary green band at 525 nm and a secondary pink band at 670 nm. The event peaked at approximately 02:15 UTC, lasting roughly 45 minutes before subsiding. Measurements from ground-based all-sky cameras confirmed the presence of two distinct auroral oval structures, with the lower elevation band more prominent in the southern hemisphere of the globe, aligning with auroral drift models that correlate with the orientation of the interplanetary magnetic field. _2_ The clarity of the event was exceptional; atmospheric scattering was minimal due to low humidity levels, and the absence of cloud cover allowed for uninterrupted visual observation. Photographic records captured a streak of green across the western horizon and a faint pink scale on the eastern sky. Spectrophotometric analysis of the visible light spectrum indicated an energy flux of approximately 1.2 kW/m², a value that is within the typical range for auroral displays at comparable latitudes. Analysts suggest that the June 2024 solar activity cycle, including a coronal mass ejection late in January, contributed to the concentration of energetic particles responsible for this illumination. _3_ For future observers wishing to replicate the viewing experience, the British Geological Survey recommends scheduling observations around new moon phases to reduce lunar interference, typically between late October and early March. The use of dark-sky compliant lanterns and static mounts for optical devices is advised to improve photometric accuracy. Public outreach programs, such as the Royal Observatory’s annual sky-watching events, provide guided observation sessions during peak forecast periods. The UK Met Office’s Enhanced Space Weather Forecast System will disseminate real-time alerts during periods of increased geomagnetic activity, enabling both amateur and professional observers to plan their activities accordingly. This documented event underscores the growing feasibility of auroral observations in lower latitudes, facilitated by heightened solar activity and improved ground-based monitoring infrastructure.
