At 18.20UT from the Isle of Arran I was looking west south west trying to find Comet C/2025 A6 Lemmon. Just above the horizon on the background hills a white blob appeared from below the horizon and moved south. Could this have been a spacecraft launch? Grateful if anyone else saw it and they were able to identify it if they might comment. (Unfortunately my camera was set for 15 seconds to try and image the comet so the object seen appears simply as a big white blob!)
