These luminous light pillars were seen from Orekhovo, about 75 km north of St. Petersburg, Russia, rising directly upwards from street lights during the occurrence of diamond dust in very cold weather. The temperature at the time was around –27 °C.
Diamond dust consists of very small ice crystals, often so tiny that they appear suspended in the air. The light pillars are a halo phenomenon formed by the reflection of light by plate-shaped ice crystals.
