I was standing in the yard looking at the night sky. i noticed what appeared as a star through the branches of a tree. it seemed to disappear and reappear so my first assumption was the tree branches were blowing. since there was no noticeable wind i moved to a clear view of the sky and observed what appeared to be a star hovering normally in the sky except that it was flitting back-and-forth and up-and-down, sometimes in a circular motion while maintaining its relative position in the sky. my first thought was my eyes were playing a trick on me so i focused on another star and watched to see if the motion was duplicated. it was not. i asked my wife to confirm what i was seeing and she agreed that she also saw motion. to be more certain i described the motion i was seeing and she confirmed seeing the same thing. it is 11:05 pm and the object is still in view west northwest of lewisburg, west virginia, approximately 30° above the horizon. it appears to be roughly 1/4-1/8 the brightness of venus. i've been watching it for about two hours and it appears to be moving on track with the rest of the celestial objects, however it does still appear to flit about.
