A Sun Pillar over Norway
Explanation: Have you ever seen a
sun pillar? When the air is cold and the Sun is rising or
setting, falling ice
crystals can reflect sunlight and create an
unusual column of light. Ice sometimes forms flat, six-sided
shaped crystals as it falls from high-level
clouds.
Air resistance causes these crystals to
lie nearly flat much of the time as they flutter to the ground. Sunlight reflects off crystals that are
properly aligned, creating the sun-
sun-pillar effect. In the featured picture taken last week, a
sun-pillar reflects light from a
Sun setting over
Fensfjorden,
Norway.

Must be a metaphor because no fire is involved. Fire is a chemical reaction. This is an optical reaction of light and ice.

Maybe it got fixed, thanks to your post. At least a nice, funny image comes up for me now.
And the first link:
sun pillar going to
www.atoptics.co.uk ... that is
fantastic. Such a treasure-trove of atmospheric effects I have never seen.
