glory Provided there is a mist of fairly uniform sized droplets,
glories can be found in many places. Till Credner and Sven Kohle
this glory and Brocken shadow in a forest on the island of Tenerife
in May 2000.
In the opposite direction they photographed
a corona and the two images are an interesting test
of theory because the mist droplets forming each were very probably
of the same size.
The corona image has several rings which, knowing the image
scale, can be well matched to a simulation with 13.5 micron
diameter droplets. Does the glory also match? There are fewer
details against which to fit but the complete innermost ring
and fragments of the next do match those of the simulated glory
(right) for the same droplets.
