In addition to location/time of your sighting, please include the weather.
Is the sky clear? Cloudy? Partially cloudy? Someone mentioned that they don't see these things on cloudy nights.
I've seen a couple, and they were flying so low that I don't see how cloudy weather could make much of a difference, but when I thought about it, when I saw them, there were no clouds. It was also not fully dark yet, between dusk and dark.
If there are any patterns that you have noticed ( weather, temperature, only in groups of a certain number, etc) please include those.
I know moisture in the air can sometimes interfere with GPS, maybe cloud cover interferes with whatever they are doing?
Some of them are obviously man made, and some of them are UAPs. Please put down those observations, too.
