I had a good view of object for some 10 seconds from my bay window which has a panoramic view of the coast. Flight seemed roughly parallel to our coast towards Lochgilphead direction, not very high in sky as i noticed it from back of room initially then from bay window. It had a long trail mainly white but I thought it had some green as well. Initially thought it was a big firework from local hotel below but too large and very straight trajectory. Regret not having been quicker with my phone camera! I have small telescope and look at Jupiter moons etc.
