It was the sixth day of the Carnival Fantasy cruise and we were docked at Port Nassau in the Bahamas.Aug 21 2015. I was on the sky deck and I pointed my cell phone at the sky and tapped the camera 5 times to take a series of pictures of the sky. It was bright and sunny and I wasn't able to look at what I was photographing so I just pointed toward the sky and pushed the button. Later that night I looked at the photos and some strange object that was a green orb surrounded by a purple light was in the picture. Object showed up in the fourth of the five pictures I took five photos in a five to ten second time.. I went back and looked at the first three pictures and the orb was in all of the photos but smaller, harder to see, but it was in various strange different locations. The pictures need to zoom in but it is large and neon green in color with a violet color surrounding it. I figured I should share the pictures with experts. 0.
