Wednesday was our 5th day of our Tansatlantic crossing. Today we spent packing our suitcases which have to be put out for pickup by tomorrow evening. One more day at sea tomorrow and it should be warmer.
We were sailing across the Sargasso Sea, It is bounded byfour ocean currents and is the only sea that does not border on land.
Waiting for sunset
At this point I switched to video mode to record the rest of the sun sinking below the horion. At this point, I have not figured out how to zoom in on the video to see if there was another green flash but I have been told there was one.
Green flashes are caused by a discrete change in temperature as a function of altitude at the horizon. This phenomena is actually acts like a prism separating the different colors of sunlight. Recall that green is a combination of the primary colors of yellow and blue. There are, in fact, occasionally blue flashes.
