“A Green Flash from the Sun” is copyrighted by Pekka Parviainen (Polar Image). NASA has permission to show it and we don't, so it isn't on this card.
See it on NASA's siteThe green flash is a real, well-understood atmospheric phenomenon, not a myth. Just as the setting or rising Sun disappears or appears, a brief, startling green glimmer can be seen. It requires a low, distant horizon and lasts only a few seconds, caused by the bending of light through Earth's atmosphere.
