What’s an aurora borealis ?
« An aurora borealis is a natural light, more often green, display in the sky particularly in the high latitude regions, and caused by the collision of energetic charged particles with atoms in thermosphere. Most aurorae occur in a band known as the auroral zone, which is typically 3° to 6° in latitudinal extent and at all local times or longitudes. The auroral zone is typically 10° to 20° from the magnetic pole defined by the axis of the Earth’s magnetic dipole. »*
In other words less scientifics, an aurora borealis is a wonderful show that the Yukon sky allows us to see once in a while. Two days now that magic is in the air. The variety of colors that the pretty Aurora is offering us is intense; this time, she’s not only filling our apples with an electric green but also with shades of purple and yellow. It’s not only a greenish powder in the horizon, but a stretch of wonder everywhere around us. Aurora seems to embrace us ’til suffocation, to envelop us with her long and bracing colored hair. The quick and rhythmic dance she’s performing creates a lively music in our mind. By a campfire, we’ve been long waiting for her this past few days, sometimes to insomnia. Marshmallows have been roasted, beers have been drunk, bananas have been burnt, time was making itself languishing and inviting. But it was worth the effort. For nothing I would exchanged those long hours of patience to keep a watch on the horizon until my neck is stiff. And my apples will never get tired of this spectacle.
