I was at home and ready to go to bed and turned off the lights. when approached the window which was open, i observed two green light hovering over the creek about 100 feet from at about eye level. I was on second floor. Took video and activated my theodolite for exact parameters. I run outside, it was the same two green lights were hovering with same pattern about 15 minutes. Could of been also projectors from down from creek side. Pattern of movement was steady and synchronized, about 5 minutes later few more 5 orbs or lights joined the circle of lights. Got exited and eventually and walked away. When next time I looked 30 minutes later lights were no longer there.
