Strange lights that moved as if an hourglass on its side, which rolled across the night sky.Between ten and eleven p.m. in the second week of March, during a crescent moon which hung in the western sky, I thought it was a perfect night for stargazing.There is a mid-sized tree in the center of our backyard which obscrued any clear view. I seen that my best bet to have the clearest view of the night sky would be on the roof of our lean-to.After making myself comfortable, laying on my back and hands behind my head, I had a perfectly view to the north and southeast. I was able to see clearly to the south at about 35°. The roof of our house blocked everything beneath that. To the west, there is several thirty to forty foot trees, which were bare of leaves, but still making it too cluttered for a decent view that way.The moon was showing through those trees, and was in the sky at about 75° when I first settled in. The stars were very bright that night. And for early March, it was very comfortable to be outside. Completely still, no wind whatsoever.I had probably been stargazing between 45-minutes to an hour. The moon loomed at 30° in the western sky. Four dim white lights coming from direct south on a straight northern route, flew right over the house. They passed directly above me as I lay on top the roof of the lean-to. The Orion constellation was to the southeast, which was my focus at that moment and my clearest view of the sky.The lights cought my attention the moment they appeared over the roof of the house. I'm guessing within a quarter mile or so south of the house. The four lights were dim, white, and appearing to be two seperate objects moving at a fairly quick pace and very close to each other like in a wingman formation.I have no idea how the objects were shaped. Nor even trying to imagine how they might look! Because the way these lights moved across the sky had me, not only jumping with joy as I knew I was seeing a bonified UFO, but also left me completely baffled as to how they could possibly have looked.I could, however, see that each object had two lights which I am sure were each set on either side of the object. I'm guessing the objects were only a few thousand feet from the ground, and by the distance the lights were apart from each other. The objects were likely the size of a small plane. Maybe even as small as a car or truck. But it was the way they moved across the sky that has left me clueless.As the objects passed overhead there was not a sound. All I could see were the four lights. I knew it had to have been two objects, each with a pair of lights. Imagine holding a dim light in each hand. Arms outstretched horizontally​. Now move your arms in a rolling motion. As the left side rolls forward, the right side rolls opposite. As if in the shape of an hourglass rolling on its side. Only it wouldn't be shaped like an hourglass. Its just the only thing I can think in comparison.The event lasted no more than ten seconds. It was very dark that night, and I was able to keep my sights on the lights until they passed beyond the horizon, which was only a couple miles to the north because they were at such a low altitude.I googled the description of what I seen of the object and the way in which it moved, but was not able to find anything that seemed similar. I did, however, come across this website, and thought by posting my account in the most detail I can give. Maybe someone else has seen a similar object and can share with how the object possibly looks. I'm intrigued.((NUFORC Note: Source of report indicates that the date is approximate. PD))
