Tony West

Tony West took this picture of a phenomena known as Parhelia, or 'Sundogs' which can form on a horizontal line either side of the 22 degree halo around the Sun, and are caused by refraction through hexagonal plate ice crystals. Sometimes the halo can be seen and sometimes it is not present. The same effect can occur around the Moon, when the phenomena is then called 'Parselena' or mock Moons.

Tony took these pictures of the sun showing solar prominences through the society's new Coronado solar telescope. (PST)
