on june first i was at the lake with some friends and i saw these 3 stars that formed an equilateral triangle start moving across the sky. all 3 moved at the same speed and kept the form. like out of no where they just started moving.... what was i looking at. was it satelites or something? can anyone tell me? i saw the exact same thing 4 years ago.. help? i have asked my astronomy teacher at school and he was about as baffled as i was..
