Five reddish orange lights moving at very fast , floating speeds in a formation. Dog got agitated as it got closer.I live just south of Puerto Vallarta in Conchas Chinas. Three friends and myself were sitting outside looking up at the stars from my deck around the pool. I looked over to a radio tower that is approximately 1 mile from my house. I noticed three lights that I thought at first were balloons and I told my friends to look. Everyone thought that it was indeed baloons until they broke into a formation of first three, then four, then five reddish orangish almost squiggly like lights. They were moving in a formation at a very high speed. When they were in a direct line to my house and also a short distance afterward, my dog became very agitated and started to whine and cry. None of us heard any sounds, nor did we feel any vibrations. These lights were traveling at a very high speed, almost similar to when you see a satellite in the sky but they were only about 1500 to 2000 feet up in the air. We watched them for about 50 seconds (maybe less) until they were rendered invisible to us due to the city lights. We are all in agreement that none of us has ever seen anything like this. When first spotted we all thought that it was balloons, so I guess it started out as an oval type of shape and then it turned into more of a squiggly shape. There was one prominately on the top that was visible at all times. Then we were able to see two more that basically formed a triangle type formation, followed by two more that were below in a triangle type line.
