How do you know when moon rise is going to be?

Answer 1

The movements of the Sun, Earth, and Moon are known quite precisely. This knowledge allows astronomers to predict where and when they will be aligned in a way that produces an eclipse. They can predict how long the eclipse will last, and can plot (in the case of a solar eclipse) the path the eclipse will follow along the surface of the earth. Eclipses could be predicted in ancient times, at least locally. By plotting the occurances of the New Moon, its different times and its varying proximity to the sun, and by comparing this with the ecliptic (the sun's path across the sky) they could calculate when the New Moon and the sun would occupy the same point in the sky.

Answer 2

Today, there are apps and other software available to help you predict the moon rise on a daily basis. Manually, you can predict the moon rise by knowing which phase the moon is in and your longitude and latitude.

Answer 3

Calculating moonrise is a mathematically complex astronomical problem, but there are books that explain the process and provide some algorithms: * Meus, J. 1999. Astronomical Algorithms. 2nd Ed. Wibbell-Bell, Inc. * Duffett-Smith, Peter. 1989. Practical Astronomy with your Calculator. 3rd Ed. Cambridge Univ. Press. * Montenbruck, Oliver, Pfleger, Thomas. 2000. Astronomy on the Personal Computer (with CD-ROM). 4th Ed. Springer-Verlag.

And there are Web sites that will perform the calculations for you, and there are guides on the subject by professional photographers. Please see the Related Links to some of these Web sites.

Answer 4

There are a few almanacs published annually in the $5 - $10 range that will give you more information about such subjects than you could ever want. *Additional* The actual calculating is taken from the previous rise times and adding or subracting time from the earths tilt.

Answer 5

over the course of a week or month or a whole year, you time when the moon hits the same spot in the sky and record the time. Make a chart and see the variations from day to day, week to week, etc

Answer 6

-- Go outside at any convenient time.
-- Look into the sky.
-- If you see white or gray, it is not a good time to perform this observation. Go back inside.
-- If you see blue, then look for a big yellow thing in the sky. It is the sun. Do not gaze at it.
-- If you see black in the sky, then conditions are ideal for this demonstration. Put your jacket on,
and prepare to look around for a while.
-- Look around in the sky, always looking in a direction above 'level'. If you look below 'level',
then the objects you see are not in the sky, and are irrelevant to this discussion.
-- The hundreds of tiny, point-like lights scattered in every direction throughout the sky are the 'stars'.
They resemble the sun in many ways. The most significant difference is their much greater distance.
-- Ignoring the stars, look for any large, bright lights. You may see several of these.
----- If there are several that appear identical, they are street lights, and may be ignored.
----- If there are one or more that move rapidly through the sky, they are aircraft or UFOs,
and they may likewise be ignored.
----- If there is one that is large and bright, does not appear to move, and has no visible duplicate
in any direction ... especially if it has the shape of only a PART of a circle ... then that is the Moon
which you seek.

Answer 7

The moons cycles at 28 days. Find the day of the phase you want to see in January in the month you are in and count 28 day months for as long as it is til next January. Use your calendar and every four weeks should be a moon cycle. It should be close. Some calendars have the phases of the moon on them.

Answer 8

The same way as the Sun (in and from the East) because this "rising" is caused by the rotation of the Earth on its axis.

Answer 9

The cycles of the moon are a little more than 28 days, so get out your calender and count 28 days from the last full moon, assuming the lunar cycles are not already printed on your calendar.

Answer 10

you can predict them but does not mean that your predictions are right

You can calculate when they will be to the exact time.
