White light over Sens, FranceThat evening on returning home, I saw a strong white light to the east, when I watched it seemed surrounded by a blue halo and moved very quickly to the north and then disappeared without making any sound.I was astounded.I do not know what altitude was the object, the sky was clear and it was night.This was not a satellite or an airplane, they are seen regularly around here (100 km / 60 miles south-east of Paris) Then a few seconds later an airliner coming from the south flew not far from the area.Sorry for the lack of information.
