Iceland In Winter – 2. The South-West

Northern Light (Aurora Borealis) is a big attraction in the Icelandic winter, but it’s not so easy to catch. It depends on the intensity of the solar wind, the interaction between the interplanetary and the earth magnetic fields and – obviously – the weather, all factors on which the human will has no influence whatsoever.

Aurora Borealisis (Northern Light) is the result of electrons colliding with the upper reaches of Earth’s atmosphere. Protons cause faint and diffuse aurora, usually not easily visible to the human eye. (NOAA–National Oceanic and Atmospheric Administration). Nikon D810, 24 mm (24.0 ƒ/1.4) 3″ ƒ/3.5 ISO 800
L’Aurora Boreale esercita una forte attrazione nell’inverno islandese, ma incontrarla non è poi così banale. La sua visibilità dipende dall’intensità del vento solare, dall’interazione tra i campi magnetici del Sole e della Terra e – ovviamente – dal meteo, fattori su cui la volontà umana non ha alcuna influenza (vedere anche Islanda in Estate)
