Although the northern lights display wasn’t at first visible to the naked eye, photographer P-M Hedén captured a faint green “aurorabow” in long-exposure pictures snapped September 9 from Vallentuna, 18.6 miles (30 kilometers) north of Stockholm, Sweden.
The composite picture shows not only the faint green aurora but also moonlit clouds, circular star trails, and the path of an airplane coming in for a landing at Stockholm-Arlanda Airport.
Hemeroscopium is for the Greek the place where the sun sets, an allusion to a place that exists only in our mind, in our senses. It is constantly moving and mutable, but is nonetheless real. It is enclosed, delimited and suggested by the horizon, though it is defined by light and only takes place in a precise moment of time. By Ensamble Studio & Antón García-Abril.
