A line of various sized and brightness lights passed in front of me in a period of 5 to 7 seconds then disappeared 1 by 1.

I was sitting on my side patio at around 9:15 pm which overlooks the Verde Valley all the way to Sedona. My patio faces east and the objects appeared from the north by Jerome and flew at a speed I estimate was 200 to 300 mph to the south towards Camp Verde. There were some light clouds that the objects flew under, so I estimate their altitude to be less than 5000' to 7000'. The objects were of various sizes and brightness, and some flew closer than others, but they all flew at the identical speed in a straight line and made a few maneuvers that were all perfectly synchronized with each other. I estimate I viewed them for 5 to 7 seconds before each disappeared 1 by 1 at the exact same spot. There was absolutely no sound coming from them. It was a very surreal sight that was hard to comprehend. I was on duty the next morning and before I started my shift briefed my supervisor on the incident to see if she had heard any reports from dispatch from that night with regards to what I spotted. I have viewed the Star Link satellites in the past and this was not even a close resemblance to them.
