Noticing light pillars? Here’s why you might see some in the winter

Viewers sent in photos of light pillars spotted in Madison late Tuesday night and early Wednesday morning.

These stunning displays are typically only spotted during the winter.

The pillars are caused by ice crystals in the air that reflect the lights from city lights, street lights and more. The pillars are usually only spotted when it is very cold and ice crystals are in a hexagonal shape.

People may be seeing light pillars recently because a lot of the snowflakes from recent snow falls were the six-sided type and if they are getting blown around, that could be causing the reflections.
