A common lunar puzzle involves the timing of moonrise. Folks who enjoy the outdoors and the wonders of nature may wish to commit to memory the words on the chart below.
- Moonrise (and, incidentally, the time of high tide) occurs about 50 minutes later each day than the day before.
- To determine the time of moonrise for each day of the month, just add 50 minutes for each day after a phase or subtract 50 minutes for each day prior to a new phase.
- The new Moon is invisible because the Sun blots it out.
- One or two days after the date of the new Moon, we can see it in the western sky as a thin crescent setting just after sunset.
- In following the chart below, care must be taken when using the terms Moon and midnight. These are affected by adjustments for daylight saving time and to a lesser degree by one's longitude in a particular time zone. (Sunrise and sunset, of course, are definitive times regardless of people's tamperings with the clock.)
- Since the Moon has no light of its own but merely reflects sunlight, we see a full moon rise in the east when the sun is setting in the west.
|The new Moon always rises at sunrise|
|And the first quarter at noon.|
|The full Moon always rises at sunset|
|And the last quarter at midnight.|
