i witnessed a rectangle, very bright LED type light looking S/W and est. the distance of 8 miles. It was huge. The lights shut off. GONEI looked outside my bedroom window in the Arden-Arcade area of Sacramento County at 21:41, looking South West and observed a Red/Orange RECTANGLE, very, very bright LED type light or combination of many lights.I estimate the distance of six to eight miles away and the size of approximately 200 yards wide and 100 yards high. It was huge! It appeared to be about 1000 feet in elevation. It hovered or floated around not moving too much, just up and down a little. The lights went to bright blueish and shut off, then reappeared back into the bright Red, Orange light, very intense light projection.It drifted South across my sight, same distance and elevation, then shut off. I videoed it with my tablet, but my tablet only recorded a bluish speck, but I was able to take a screenshot from the video at its most intelligible position. I blew up the speck so you can almost make out the rectangle shape. I could see it through my tablet as I was recording it and knew it wasn't recording the same brightness and color, but at least I was able to record its presence.This exact same event took place last year starting on May 13th, 2016, and continued most every night for a week and I also took phone video and pictures with my phone of that event(s).I will attempt to get a better video with my cellphone, although it is not a smart phone, it does record better than my tablet. I used my tablet because it has way better screenshot and enhancement features. I will send more reports as I witness them.
