Explanation:
What's happening in the sky?
Unusual lights appeared last week to hover above
Whitefish Bay
on the eastern edge of
Lake Superior
between the
USA and
Canada.
Unsure of the cause, the
Michigan-based astrophotographer switched camera lenses -- from
fisheye to
telephoto -- and soon realized he was seeing
light pillars: vertical
lines
of
light
over a ground source that reflect from falling
ice crystals.
As the ground temperature was above freezing, the
flat crystals likely melted as they approached the ground, creating a
lower end to the vertical light pillars.
The red ground lights originated from
wind turbines on
Ile Parisienne, a Canadian Island
visible across the bay.
