Last night was my fourth time seeing this type of thing. i also saw it on april 26th,22nd and not sure about the other two dates. a very bright shining light in the sky catches my eye. making no sound they move to the left and then back then up and back. when they light up it's very bright, but when they dim down the white light sometimes turn an orange color and i can almost make out a shape. they don't have a regular bliking time it's all different. it's more of a pulsating light than a blinking light. i would say their height varies. i have seen some very far off like next to the sars, some at jet height and some way lower. they aren't around for long. i would say i have watched them for a minute, some way less. last night the hair all over my body stood up because i felt like they were toying with me. one got my attention off of the first one i saw and when i looked for the first one again i couldn't find that one or the second. which was hard to believe because it was very very bright. right now i'm baffled as to what they are.My husband has witnessed this once but they were very far away, every other time i have seen them they have been pretty close.I have tried taking video with my phone. not sure it came out yet. i have seen them twice around 330am. once around 930pm and once around 130am.
