Me and my wife have seen lights in perfect straight line about 300 m long more or less 80 of them going from west to east

I went outside to check if bears are away from my neighbors fruit tree , it was quiet .then to my surprise I round lights started to show up above my trees .it was peach dark and the lights were quite bright so I I couldn't figure out at first what it is , when the last light appeared I realized how long it is , I called my wife to see it , she came right in time before it went behind the clouds. There was no noise coming from it , it flew very slow , about 1000 m above my house .
