I was facing west north west when i looked up and noticed a "string" of lights. there was one bright light that seemed to be leading 20 to 30 more lights. they were traveling south, maybe south east. all the lights were evenly spaced and traveling at the same speed in a perfectly straight line. this event lasted roughly 10 seconds. it would have lasted longer but it was cloudy that evening. luckily, i witnessed the event in a small break in the clouds. im not good at gauging distance, speeds, or size of the object(s), so i'm not going to speculate such things; especially at night.
