That flash of green that appears momentarily on the horizon just as the sun drops out of sight. After all these years in Hawaii this is the first time I've seen a really good flash of green at sunset. This time I was up the road from the Kawaihae harbor watching some whales and there it was - just for a second. It looked something like this although the sky was not as black as this photo from the Bishop Museum website, which explains in easy to understand terms how and why this happens
Happy Earth DAy and here is Lucy !
