Solar Halo, May 2001
Ice crystals in the atmosphere cause the effect known as a solar halo. The image shows the relatively common 22° halo round the Sun and the much rarer and fainter, parhelic circle (going up to top left) which passes through the Sun and intersects the 22° halo. It also captures a circumscribed halo which shows as a shoulder on the 22° halo - but this isn't very obvious. Taken from Newbourne, near Ipswich, in May 2001, using a 16 mm fish-eye lens.
