Posted on 06/04/2014 9:53:09 AM PDT by SunkenCiv
Explanation: Many think it is just a myth. Others think it is true but its cause isn't known. Adventurers pride themselves on having seen it. It's a green flash from the Sun. The truth is the green flash does exist and its cause is well understood. Just as the setting Sun disappears completely from view, a last glimmer appears startlingly green. The effect is typically visible only from locations with a low, distant horizon, and lasts just a few seconds. A green flash is also visible for a rising Sun, but takes better timing to spot. A dramatic green flash, as well as an even more rare red flash, was caught in the above photograph recently observed during a sunset visible from the Observatorio del Roque de Los Muchachos in the Canary Islands, Spain. The Sun itself does not turn partly green or red -- the effect is caused by layers of the Earth's atmosphere acting like a prism.

It's an atmospheric refraction effect caused by temperature gradients, IIRC.
Weird article, where they say cause unknown in the beginning, then give the cause at the end...oh well - neat pic!
Thanks a LOT for sending me on that search - heh.
Side note, did JDM frequently use lefty plots?
“Thanks to its pro-eco stance, A Flash of Green was financed by and telecast as an edition of PBS’ American Playhouse.”
That was just me trying out my Green Latern Ring, nothing to see here...
What I remember from being a young teenager reading my Grandfather's collection was more focused on living on boats, and aerobic activity with females.
I’ve seen several of these over the last 15 years while vacationing on Captiva Island (west coast of Florida). There’s a restaurant on the Island named The Green Flash. If you like to watch sunsets like I do...these are a rare but exciting ending to a beautiful west coast Florida sunset.
Alien spacecraft deploying a thermonuclear device ???
(Then again, the Sun *is* one HUGH H-bomb ;)
Sailors have always known about green flash. At sea a green flash can be observed in about 50% of sunsets.
In brightest day, in blackest night,
No evil shall escape my sight
Let those who worship evil's might,
Beware my power... Green Lantern's light!
Wife is better at spotting them than me, I tell her she is just more suggestive............

That was one of his novels I enjoyed. (Oh, heck, I enjoy them ALL!)
Funny thing is someone made a movie / PBS show of the novel (any way our local PBS station played it). It was so boring I couldn’t watch it. The novel just didn’t translate OR the scriptwriters blew it. I’m gonna go with “scriptwriters blew it,” since “The Executioners” translated SO DARN WELL into Cape Fear.

That is the Travis McGee series, thackney.
JDM also wrote a lot about Florida life — real estate development with corruption, weather, and so on.
He also wrote a science fiction series that has a kind of C. S. Lewis feel to it without the religious overtones.
Also see the DELIGHTFUL “The Girl, The Gold Watch, and Everything.” (I’m STILL looking for the T.V. mini-series made from that novel.)
Sorry to go on, but I’m a fan since the 1960s. Blab, balb...
I have looked for the green flash but have never seen it.
Nice pic. I thought the flash would be bigger than that.
What were those named? It has been decades since I've read his work but I used to wear out the books my Grandpa had.
What were those named?
Wine of Dreamers
Ballroom of the Skies
Short SF stories: Other Times, Other Worlds
Fantasy: The Girl, The Gold Watch & Everything (novel)
- Robert Hayes and Pam Dawber (miscast brunette)
