The Moon At what time of day does the Moon rise and set? When does it cross your meridian (this is another way of asking "When is it highest in the sky?")? Well, that will depend on the phase. The phase will determine the location of the Moon relative to the Sun. Your location relative to the Sun will determine what time of day it is. Remember, we base our time system upon the location of the Sun - so if the Sun is on your meridian (high in the sky), then it is Noon at the part of the Earth you are located at. A person at a location on the opposite side of the Earth from you would be looking at their watch and noting that it is midnight. Of course, daylight savings time, and the rather irregular way that time zones are set up, may actually mean that it is not exactly noon or midnight, but we'll make it simple and assume that it is. Take a look at the set up shown in Figure 9. If you were at the point labeled "noon," the Sun would be high in the sky, but the Moon would be on the horizon - it would be rising. If you were

A person at the midnight position would see the Moon on the horizon, setting. Remember, as viewed from above the North pole, all motions are counter-clockwise. The Earth will be spinning around while the Moon remains in about the same position (the first quarter phase location). All day, anyone seeing the Moon would see a First Quarter moon. To see the Moon you must be located on the side of the Earth that is toward the Moon, so the person located at the 6 AM spot wouldn't see the First Quarter Moon, and neither would anyone located at a position corresponding to 1 AM, 2 AM, 3 AM. .. all the way until Noon. It would take a day or two for there to be a noticeable change in the Moon's rising and setting times....
