WOW Aurora on Ice

Aurora on Ice:

Aurora on Ice

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.
