Aurora and Unusual Clouds Over Iceland
Explanation: What's happening in the sky? On this cold winter night in Iceland, quite a lot. First, in the foreground, lies the largest glacier in Iceland : Vatnajokull . On the far left, bright green auroras appear to emanate from the glacier as if it was a volcano . Aurora light is reflected by the foreground lake Jkulsrln . On the far right is a long and unusual lenticular cloud tinged with green light emitted from another aurora well behind it. Just above this lenticular cloud are unusual iridescent lenticular clouds displaying a broad spectral range of colors. Far beyond the lenticular is the setting Moon , while far beyond even the Moon are setting stars . The above image was captured in late March of 2012.
