1)husband and i were sitting in our outdoor hot tub in dahlonega ga. time was approx. 8:05 or 8:06pm. clear skies. temperature approximately 50 degrees. 4-3-2018 we are situated approximately 1800 feet in elevation. 2)noticed the movement of light. we watch for satellites and falling stars on a nightly basis. 3)thought it was a falling star, but as i continued to watch it i saw multiple lights in a distinct v shape moving in a straight line. 4)i saw 7-10 dim lights moving in a n-nw straight line direction. the lights were shaped in formation as if they outlined a narrow arrow head. speed was as fast or a bit faster than a plane. 5)i was watching intently as the light moved but then noticed that there were several lights.As the object stayed unchanged in my sightline i was sure it wasn't anything i had seen before. the lights were dim but the formation of the lights made it apparent. the lights did not change intensity even as they disappeared behind the trees. there was no noise that could be distinguished. 6) the lights remained in formation as they went behind the tree line and out of sight.
