The sаme three Eаrth-bаsed views оf the mооn are shown again below.  The space-based diagram below shows six possible positions (A - F) for observers on Earth who see the Moon as it shown above. Study the space-based diagram and pick the correct position for the observer who sees the Moon as it is shown in each of the three Earth-based diagrams A - C. IN THE DIAGRAM BELOW, ASSUME THAT POSITION 5 IS DIRECTLY ABOVE OBSERVER E AND POSITION 9 IS DIRECTLY ABOVE OBSERVER C. You may find it easier to answer this question if you translate (in your own drawing) each of the Earth-based diagrams to a space-based diagram with the observer in the correct position on Earth. The correct observer location for moon A is [position 1] The correct observer location  for moon B is [position 2] The correct observer location for moon C is [position 3]
