?Goleuadau?r Gogledd? ? Mathew Browne Wales, United Kingdom The title of this image, ?Goleuadau?r Gogledd,? translates to ?Northern Lights? in Welsh. Finding the accurate translation proved challenging, as this phrase isn?t commonly used in everyday conversations here in South Wales. Witnessing the aurora borealis this far south is a rare occurrence, and capturing it at an iconic location like Paxton?s Tower adds to its uniqueness. Paxton?s Tower, a hilltop folly with a history spanning over 200 years, overlooks the picturesque Carmarthenshire countryside. For over an hour, the horizon beyond the clouds emitted hues of green and pink. However, for a brief yet magical moment, the sky came alive with impressive pink pillars, visible to the naked eye
