I had just gotten into California and was relaxing in my hotel room. I took a photo of the view from the hotel room balcony and noticed that there was some air traffic across the bay from where I was, but didn't think much of it. a short while later that there was a glowing shape in the sky. it hovered there and i dismissed it as some sort of military activity as I was not familiar with the area. I later decided that this was unlikely because i had seen aircraft in the area and they were not glowing, or the same shape. i lost sight because I was flustered with the new experiences of the city and went to do other things besides sit on the balcony. I am unsure if it moved, but i think that it swayed gently in semi-large fashion. Date stamps for the attached photos are the same as on report. time stamps are as follows in order of attachment: 23:03, 23:03, 23:03, 23:04.
