seen object then plane came into view, object viered left and up followed then exited up and to the leftI saw a big bright circle, about 8 times bigger than a star with like a halo around it and seen that it was moving. I watched it for a few seconds and seen that it went up and to the left some when an airplane came into view of my window, I could see this because the circle of light got smaller and went up.The airplane continued in a straight line to the southeast and the object followed it a short distance above and to the north of it slightly.The airplane went out of sight of my window and the object went to the north and up until I could no longer see either one from my window.
