Small sparkling lights in the air/skyMy dog awakened me at the above time to go out to my large fenced yard to her business. It was a clear, starry night with temps hovering at zero F. As I was calling her back in I noticed these 'firefly'-like golden lights in the air/sky moving about. I could not tell if they were indeed small and close by in the pine trees, fifty feet away, or in the sky higher up and farther away behind the trees. I tried to think of a rational way at looking at these lights but could not. They were all tightly grouped but moving erratically with a sparkling effect. They were in the NW part of the sky or closer in my yard and in the trees. I did see a bright light traveling in the same direction, NW, and away, at the speed of a plane, but could hear no sound and don't know if it were connected in any way to these sparkling lights. As I went further in the yard to get a closer look they all suddenly just disappeared. I stayed out in the yard for another five minutes but they did not return and I saw nothing else unusual.
