Glory

Sometimes described by air travellers as a small circular rainbow the glory is one of the harder effects to find at ground level because you need to be above most of the cloud or fog layer.
Often seen from aircraft.			Can be sometimes be seen with a fogbow.
On rare occasions can be very large.			Shows a number of polarisation effects
See Les Cowley's Atmospheric Optics site for a detailed explanation of how the glory is formed. The droplet sizes on the following pages were estimated using his IRIS software.
