| Pillars & Plates Light pillars imaged in Finland 5-8th January by Jukka Ruoskanen (Halo site). The crystal samples taken during the displays show the variety of very thin and clear plates that created them by reflecting the ground lights towards the eye and camera. Few crystals are regular hexagons and many have indented or decorated faces. Pillars (both sun and light) unlike other ice halos are undemanding of optical perfection.
