|Morning Run Glory, Belgium ~
Mist and sun combine to produce a ringed glory. Witnessed by Bert Bruynooghe while running on the dykes alongside the marshes at Gentbrugge.

|Droplets 5-50 micron diameter produce glories. They diffract sunlight.
A fogbow and corona are part of the same outcome.
Larger drops, like raindrops, still diffract light but their glory is small and unnoticeable.
Refraction rather than diffraction dominate. No glory or corona but instead a a sharp rainbow.
Search for a glory whenever there is sunlight and mist (or cloud). An airplane is good. Or a mountain. But a ship's rail over a cool sea, a milk processing factory, a dyke or sometimes a field will suffice. The key is the sunlight shining on or through enough mist directly opposite. As seen above, only a metre or so of mist is enough.
