Fantastic pink auroras! The colours of the northern lights are determined by a number of factors: - the composition of gases in Earth's atmosphere - the altitude where the aurora occurs - the density of the atmosphere - the level of energy involved Green is the most common colour seen from the ground and is produced when charged particles collide with oxygen molecules at altitudes of 100 to 300 km. Occasionally, the lower edge of an aurora will have a pink or dark red fringe, which is produced by nitrogen molecules at altitudes of around 100 km.

In Iceland, select hotels now offer a magical perk: the “Northern Lights wake-up button.” Guests who opt in are placed on an alert list, and when auroras appear, staff call or even knock on doors so no one misses the spectacle.

In Scottish Gaelic folklore, the Northern Lights are known as the Na Fir-Chlis – 'the Nimble Men', this beautiful poem from 'Wain', reimagines them as queer men dancing together in the skies above 💙💚🩵💜
