Small light, first mistaken for a bright star, begins moving slowly downward in a zigzagging pattern, before slowly dimming out.Yesterday evening, my boyfriend and I were about to go out and run a couple of errands. As we walked through the parking lot, I glanced up at the sky as I usually do. I first noted Venus, then turned to look at Orion (roughly to the East) and said "Look, Orion!" (typical behaviour for me). To the left upper side of the constellation, I noticed a very bright star that didn't seem to belong there, but I shrugged it off and turned to get into the car, when my boyfriend, who was still looking up at the sky said "A UFO!" I turned back to see that the white dot of light that I'd first mistaken for a bright star was slowly moving downward through the field of the Orion constellation. The light zigzagged slightly as it moved downward and toward the left. The lack of blinking and coloured lights, as well as the pattern of movement made both my boyfriend and myself remark that it couldn't be a place. The light was also far too small/far away to be a helicoptor. After about a minute or less, the light had reached the area right below the constellation, when it began to dim until it had disappeared entirely. We waited a bit to see if it would return, then got into the car. As we were exiting the parking lot, I looked up toward Orion again, and this time I did see an airplane traveling northeast, though I doubt that was related. I am a 23 year old female and have lived in Paducah, Kentucky my entire life. My boyfriend is 32 and originally from Guadalajara, Mexico.
