Bright white satellite looking object North Eastern sky rapid speeds vertical and horizontal object turns blue as it changes directionsOut of the two videos I shot, you can see this satellite looking object zig zag through the sky turning a bright blue color over and over. I was not able to tell the shape of the object by sight or in my god awful video I took of it. I saw a bright white star looking object, looked like a satellite in the sky but much brighter. This object appears, moves horizontally at about the speed of a small aircraft, then went vertical at a rapid speed. This object then continued to move horizontally back and forth occasionally moving higher in the sky and seeming to turn a blue color as it changed it's direction instantly. I tried to drive in the direction I saw it after I lost sight of it, but I couldn't find an answer to what it was. I talked to a couple different police officers on duty near the airport, I called air traffic control and I am waiting for a call back.Today was my second sighting of this object flying through the early morning sky, same location and about the same time. The first time I saw this object was 06/19/17 in the North Eastern sky while observing Venus between 3am and 4am PST. I tried to wake my wife up that night to show her, and of course it was gone by the time she came out. I went out and bought a Nikon p900 to get some close up shots of the moon, Jupiter and Saturn this week. Early this morning I went around the same time as I did on the 19th in search of this object, and there it was. I ran inside grabbed my camera that I don't have a clue how to operate and shot this footage. I did a terrible job shooting the footage, but hopefully it's enough to show what I was looking at.
