This was the sun about to set in the sea on September 29. Because of the clouds, the sun had a gradient from yellow to red, and green rim-a narrow green upper edge. At the same time, there were 3 sunspots and a plane flying by! The green rim that occurs when the sun sets is mainly because green light is more refracted than red light. For more details on the green rim phenomenon, please refer to the description of the following webpage: https://atoptics.co.uk/atoptics/gf15.htm.
