APOD: Aurora on Ice (2015 Feb 13)

Post by APOD Robot » Fri Feb 13, 2015 5:06 am

Image Aurora on Ice

Explanation: Not from a snowglobe, this expansive fisheye view of ice and sky was captured on February 1, from Jökulsárlón Beach, southeast Iceland, planet Earth. Chunks of glacial ice on the black sand beach glisten in the light of a nearly full moon surrounded by a shining halo. The 22 degree lunar halo itself is created by ice crystals in high, thin clouds refracting the moonlight. Despite the bright moonlight, curtains of aurora still dance through the surreal scene. In early February, their activity was triggered by Earth's restless magnetosphere and the energetic wind from a coronal hole near the Sun's south pole. Bright Jupiter, also near opposition, is visible at the left, beyond the icy lunar halo.

Lovely image! And the moon is reflected in the large ice crystals on the ground, as opposed to being refracted through them.

Thanks for sharing that. A balmy day on Mars? On the other hand, the low tonight will evidently be about -72 C. :(

Does anyone want to guess what the halo around the Moon in this image remind me of? :D
