Green flash at De
Panne, Belgium  . A frame from the sequence
imaged by Forian
Schaaf on 31st March '03. The I-Mir
flash (close up) is produced by a layer
of warm air just above the sea. Clear air is necessary for the
most brilliant green flashes but clear skies are not. Here the
sky is covered by high cloud but this does not overly influence
the flash. Image ©Florian Schaaf, shown
