Lunch time today (30 August 2018) provided a surprise with a rare atmospheric sight over Sydney Observatory. Surrounding the Sun was a 22° halo, sundogs and a parhelic circle. The display was caused by cold air and high altitude hexagonal-shaped ice crystals. This was a special treat as these atmospheric effects are rarely seen in Sydney, especially when the Sun is high in the sky. The mosaic below is a series of six images and was taken at 1:10pm (EST) when the Sun was 43° in altitude.
