Donald J. Barry answered on November 30, 1999, A: If the moon is visible in the western sky after sunset, then it is near the sun in the sky (because the sun also sets in the west). In this configuration, the sunlight falls mainly on the back side of the moon as seen from the Earth, and we only see a crescent of light on the thin region visible from both the sun and the earth. If the moon is rising as the sun is setting, then the two objects are nearly opposite one another in the sky. So we view the moon from the same vantage as the sun would (it would be as if one person (the sun) were looking over another's shoulder (the earth) at a third person (the moon). Anywhere the sun shines on the moon, we see. So the moon looks full.
The "First Quarter" is not a duration or period of time. It's a single point in time ... the first
moment after a Full Moon when the moon appears 50% illuminated. The moment arrives
roughly 7days 9hours after the moment of New Moon.
When the moon is full, the Sun and the Moon are on opposite sides of the Earth. So if the Moon is full, and the full moon is on the western horizon, then the sun is just below the Eastern horizon.
When the Sun is just below the Eastern horizon, then the sun is coming up and we call this "dawn".
If the First Quarter moon is rising, then the moon is a quarter of the sky behind the sun, and it
rises a quarter of the day after the sun ... six hours after the sun-rise, or nominally Noon.
The full moon will be visible in the western sky just before sunrise on Saturday, December 13, 2008.
In general, the full moon is visible in the eastern sky just at sunset, and in the western sky just at sunrise.
For a body to "transit" means that this body is passing our longitude; it is as near to straight-up as it is going to get. There's a special phrase for when the Sun transits; it is "high noon".
If Moon is "in transit", then the Moon is pretty much straight up. If the Moon is precisely full, and straight up, then the Sun must be approximately opposite. So on the other side of the world, it is "high noon".
So the time is midnight.
When the moon is at First Quarter ... roughly one week after New Moon ... it is 1/4th of a sky behind the sun. So it rises at Noon, transits at sunset, and sets at midnight ... appearing at each point 1/4 of the day after the sun is there.
The First Quarter moon rises and sets roughly 1/4 day after the sun does.
About 6 hours after sunrise, which depends on the time of year and you latitude.
A new moon rises at 6 am and sets at 6 pm with its highest point at noon. if you have the essential cosmic perspective book, its in section 2.3, fig 2.19 (pg 42 in my book).
The next Full Moon will be at 4:01 AM UCT on May 9, 2009. (Subtract 4 hours to get EDT, or subtract 7 hours to get PDT.) The time of moonrise on that day will be dependent on your location. Go to http://aa.usno.navy.mil/data/docs/RS_OneDay.php to calculate the time of moonrise and sunrise on that day.
Yes, as the moon is orbiting the Earth, the moon rises and sets at different times each day or night. All of the waxing moon phases (i.e. waxing crescent, first quarter, waxing gibbous) rise during the daytime before sunset.
No. Time time of moonrise and moonset changes each day. It is important to note, however, that the moon is always up, 24 hours a day. The only difference is that during the day that the moon is strongly outshone by the Sun and therefore difficult to see. The terms in the above answer, specifically "moonrise" and "moonset", are described the times when the moon becomes easily visible and when it begins to be overshadowed by the Sun respectively.
A first quarter moon is 90 degrees from the earth and the sun. Therefore, it rises around noon. Last quarter moons are also at 90 degrees, but the 'other' 90 degrees, 180 degrees from the first quarter position. So last quarter moons rise around midnight. The moon always rises in the east.
The moon rises and sets just like the sun, but unlike the sun moonrise and moonset can occur an any time of the day throughout the 29 day lunar month.
The moons phases do not coincide with the length of our days so there is no 'best' time to view the first quarter unless you know the position on the moon. You would need find the dates of the phases and the times of moonrise and moonset.
Are you talking about the first games or the 75th quarter quell?

Moonrise occurs about 57 times every 59 days, so on most days there is one moonrise, but about once a month there is a day without a moonrise (the moon rises a little before midnight of the previous day and a little after midnight of the following day).

Dawn.
Yes, that happens in regular years (non-leap years) that start on the weekday after the usual pay weekday. In such a year, the first quarter has 12 paydays and the third quarter has 14 paydays. So since 2013 starts on a Tuesday, 2013 will be a year like that for people who are paid every Monday. A quarter is about 13 weeks. Every 2nd quarter and the 1st quarter of every leap year is exactly 13 weeks. Therefore, those quarters will always have 13 weekly paydays, no matter what weekday is the first day of the quarter. The 1st quarter of every regular year is one day short of 13 weeks, so if Jan. 1 is the weekday after the usual pay weekday, that 1st quarter has 12 paydays. If Jan. 1 is any other weekday, that 1st quarter has 13 paydays. Every 3rd and 4th quarter has 13 weeks plus one day. So whenever the first day of a 3rd or 4th quarter is payday, the last day of the quarter is, too, giving you 14 paydays. Every time a 1st quarter has 12 paydays, the first day of the 2nd and 3rd quarters will be payday. So every time you lose a payday in the 1st quarter, you get it back in the 3rd quarter.
The New Moon can't be seen at any time of day. In addition, the first quarter moon is just rising at noon, and the third quarter moon is just setting at noon. So practically everything between first quarter and third quarter is below the horizon at noon, and not visible.
At the North Pole, the moon rises and sets about once a day, just like at any other location on Earth. However, due to its proximity to the pole, there are periods of continuous daylight in summer and continuous darkness in winter, which can affect visibility of the moonrise and moonset.
