Auroral Display from Boscastle, Cornwall – 19 January 2026
This entry documents a significant auroral display observed from Boscastle, Cornwall on the evening of 19 January 2026, during a period of enhanced geomagnetic activity.
Although aurorae are rarely visible from this latitude, sustained geomagnetic disturbance allowed auroral emissions to develop clearly above the northern horizon. The coastal location provided an unobstructed view, enabling the evolution of the display to be followed over an extended period.
The event progressed through a combination of broad red auroral skyglow and structured green lower-level emissions, with changing geometry and extent visible over time.
Representative frames from the sequence are shown below, illustrating the temporal development of the display:
19 Jan 2026 – Broad red auroral skyglow established above a strong green lower band along the northern horizon during the early observed phase of the display.
19 Jan 2026 – Intense green auroral structure dominating the lower sky, with diffuse red emission present at higher altitude, clearly separating the two emission regions.
19 Jan 2026 – Transitional phase showing curved and evolving auroral forms, indicating ongoing changes in the structure and extent of the emission.
19 Jan 2026 – Late-stage display dominated by extensive red auroral glow, with residual green structure still visible toward the northern horizon.
Additional gallery images are included below for visual context and atmosphere:
19 Jan 2026 – Auroral glow above Boscastle village, with red and green emissions visible despite foreground street lighting.
19 Jan 2026 – Soft late-phase auroral skyglow showing broad red and green colour gradients across the northern sky.
19 Jan 2026 – Diffuse green auroral emission recorded during the event, illustrating the extent of lower-altitude auroral glow.
This post has been added to the restored YaBB astronomy archive to preserve a record of a notable low-latitude auroral event observed from the Cornish coast.
