S-shaped shiny UFO Sighting very high up in the sky looked like barely more than a sparkle until I looked through my cameras 2000mm zoom lens. There was nothing else near it, very hard to focus on due to distance. Was able to snap a photo. Unfortunately there no reference for scale but this was at least as high up as a cruising plane and was out of sight within 5 minutes. mufon cms# 115058 Portland Maine 4/27/21 This Region has had 703 Reported UFO Sightings to date.
