No forecast this time. I would however like to draw your attention to a series of pictures taken in Oslo in the morning hours today.
What you will be watching by going to the website (probably copyrighted and so I can not snap and publish) is an optical illusion called light pillars.
Such light pillars may occur when it’s cold weather, colder than minus 10, and fairly low water vapor content in the air. It should not be confused with Northern Lights.
It is an optical phenomenon in which light from the light sources on the ground are refracted and reflected in small ice slab.
To form the stripes of light, the vast majority of ice slab floating around in the air are in the same orientation, often lying.
Then the refraction and reflection of light from a light source seen by the eye of the viewer is collected in a fairly concentrated beam.
Happy viewing the ten pictures, this is, I guess, a fairly unknown natural phenomena to many of you…
