I thought this was an urban legend.....cause in all my Jamaican sunsets I had never seen it once!
Until last December! I was alone & thought 'Did I really see that?!' Thankfully, someone else saw it too & confirmed it for me later!
I mentioned the green flash to someone on the pub crawl & they never heard of it before. My mind needs a lil stimulation today so I googled green flash for a true scientific explanation.
Thought I would share!
