There's two different types one blueish in color and other amber color. the blues tend to stay further up than the amber color, and do not hover as long. i've seen these "lights" consistently for a month. the amber sometimes for 5 hours. often in pairs, i've seen them singular as well as split into two and quickly go back together. they are typically over over the tree line about 1/2 mile from my house. my house guest as well as neighbors have witnessed them a number of times as well. in all kinds of weather, windy clear, raining, the length of time for amber lights seem to be increasing. i've had a helicopter that wasn't familiar fly directly overhead then leave , after observing the orb with a group of people for a lengthy time. i have no idea what they are, curious all the same. video attached should show both kinds of orbs on several different dates.
