Chevron Light Formation in Quintana Roo, Mexico.I was on vacation in the Yucatan Peninsula. My sister and I were sitting toward the ocean at approx 11:00 pm, looking at the night sky. My daughter was sitting with us and suddenly said she had to go to the restroom and left. Shortly after she left, I saw several lights moving across the sky from right to left. The lights were a soft yellowing white, in a V-shape and there were approx five lights on each side. The lights moved as one across the sky, fairly slowly and when they got to about 10 o'clock in the sky, the lights made a big sweeping U turn and then shot off very fast into the sky. My sister and I were very excited, strangely no one at the resort was around. My daughter returned and said that she went to the restroom and when she got there she wondered why she was there because she didn't have to use it.
