no sound from greenish/white light shooting very close above tree line over neighbors house in vacaville ca.I was in the back yard looking up ; the moon was to my left, when a light caught my eye above the tree under the moon in my neighbors yard. It was so quick I did not have much time to focus, there was no sound at all. There was a greenish/ white light at the beginning of it; and it kinda had a tail ,like a commit. It went in a straight line above the tree's rather close. All this leads me to believe it was not any aircraft, commit or meteor but I do not think anyone else saw this anomaly.
