Phases of the moon

In astronomy, a phase of the Moon is any of the aspects or appearances presented by the Moon as seen from Earth, determined by the portion of the Moon that is visibly illuminated by the Sun. The lunar phases vary cyclically as the Moon orbits the Earth, according to the relative positions of the Earth, the Moon, and the Sun. Since the Moon appears bright only due to the Sun's reflected light, only the half of the Moon closest to the Sun is illuminated. The lunar phase depends on the Moon's position in orbit around the Earth. This diagram looks down on Earth from the north. Earth's rotation and the Moon's orbit are both counter-clockwise here. From this diagram, we can see, for example, that the full moon will always rise at sunset, and that the waning crescent moon is high overhead around 9:00 AM local time. Lunar phases are the result of our seeing the illuminated half of the Moon at different angles. The Moon exhibits different phases as the relative positions of the Sun, Earth and Moon change, appearing as the full moon when the Sun and Moon are on opposite sides of the Earth, and becoming invisible as the new moon (also named dark moon) when they are on the same side: these two phases are called syzygies. The time between two full moons is about 29.5 days; it is longer than the time it takes the Moon to orbit the Earth since the Earth-Moon system is orbiting the Sun. The phases are not created by the shadow of the Earth on the moon (that would be a Lunar eclipse); instead, they are a result of our seeing only part of the illuminated half of the Moon. Dark Moon - Not visible New Moon - Not visible, or traditionally: first visible crescent of the Moon Waxing crescent Moon - Right 1-49% visible First quarter Moon - Right 50% visible Waxing gibbous Moon - Right 51-99% visible Full Moon - Fully visible Waning gibbous Moon - Left 51-99% visible Third quarter Moon - Left 50% visible Waning crescent Moon - Left 1-49% visible New Moon - Not visible In the southern hemisphere, the above is reversed. For example: Waxing crescent Moon - Left 1-49% visible Waning crescent Moon - Right 1-49% visible When the Sun and Moon are on opposite sides of the Earth, the Moon appears full: the moon appears as a whole disc. As the Moon orbits the earth, the moon wanes, as the amount of illuminated lunar surface reduces, until the moon effectively disappears at the New Moon, when the Moon is between the Earth and the Sun and thus the illuminated half cannot be seen at all. Gibbous (red) and crescent (blue) shapes resulting from dividing a circle with an inscribed half-ellipse. According to geometry, when a sphere is illuminated on one hemisphere and viewed from an angle, then the portion of the illuminated area visible from that angle will be observed to have the two-dimensional shape of a half-ellipse inscribed within a half-circle, where the major axis of the ellipse is the same as the diameter of the semicircular arc. If the half-ellipse is convex with respect to the half-circle, then the shape will be gibbous, and if the half-ellipse is concave with respect to the half-circle, then the shape will be a crescent. If the eccentricity of the ellipse is 1, then a half-circle will be seen; while if the eccentricity of the ellipse is 0, then either a fully-illuminated or fully-dark circular disk will be seen (i.e. a full moon or new moon). Of course, actual observations of the moon's lit area will not completely correspond with these abstract geometrical shapes, due to varying surface reflectivities, the lesser brightness of illuminated areas which are viewed at a low angle, etc. The different phases of the Moon have different names. As the moon waxes (the amount of illuminated surface is growing), the moon moves through the New Moon, Crescent Moon, First-Quarter Moon, Gibbous Moon and Full Moon phases, before returning through the Gibbous Moon, Third-quarter Moon, Crescent Moon and Old Moon phases. Old Moon and New Moon are interchangeable, although New Moon is used in preference, and Half Moon is often used to mean the First- and Third-Quarter Moons. It would seem that when the Moon comes between the Earth and the Sun (ie. at a New Moon) its shadow should fall on the Earth, causing a solar eclipse. Likewise, during a Full Moon, we might expect the Earth's shadow to be visible on the Moon — a lunar eclipse. This is, in fact, how eclipses happen, but they don't happen every Full or New Moon. This is because the plane of the Moon's orbit around the Earth is tilted by about 5 degrees with respect to the Earth's orbit around the Sun, meaning that at the New and Full Moons the Moon is usually above or below a direct line through the Earth and Sun. An eclipse can only occur when the moon is positioned at, or very nearly at, one of its nodes (or crossing points between the moon's orbital path and the ecliptic). This happens twice a year (roughly), and so there are between 4 and 7 eclipses in a calendar year. Most of these are quite insignificant; major eclipses of the Moon or Sun are rather rare and newsworthy events. Casual observers will not typically notice a waxing crescent Moon until about 60 hours after it has passed conjunction with the Sun; but some individuals have crafted a hobby out of attempting to view the Moon after a much shorter interval than this. Informal "records" and their confirmability vary; some have claimed to have seen a Moon in as little as 12 hours after the moment of conjunction. Three factors increase the likelihood of spying a very "young" Moon: First, the angle the Moon makes with the ecliptic must be favourable for the applicable side of the Earth — the optimum scenario for this would be a new moon that falls in mid-March in the Northern Hemisphere or mid-September in the Southern Hemisphere; second, the Moon should be at or near perigee, causing it to appear to move faster (and hence draw away from the Sun sooner); and third, the new Moon must be at or near its maximum separation from the node in a favourable direction based on the hemisphere of the observer. These same principles can be applied to sight a very "old" Moon just before conjunction (with the best time of year being very early autumn for that side of the Earth), but this is far less commonly pursued. A first-quarter Moon follows a daily path in the sky corresponding to that of the Sun after three months. Hence it comes at the highest altitude — or "runs high" — at or near the vernal equinox. Similarly, a full moon comes highest at the winter solstice, a last quarter Moon at the autumnal equinox, and a (almost) new Moon at the summer solstice (the opposite of "runs high" is "rides low" — a first-quarter moon at or near the autumnal equinox, a full moon at the summer solstice, etc.). This also means that a first-quarter Moon will not necessarily set at midnight, nor must a last-quarter Moon rise at midnight; both would do so at the equator, but north or south of this the time of rising or setting will vary by a progressively wider margin as the latitude increases; indeed, a first-quarter Moon in the late winter or early spring would remain constantly above the horizon in the polar regions (as would a last-quarter moon in the late summer or early autumn). For an animation of how the Moon appears from Earth over the course of an orbit, see libration.

If the right side of the Moon is dark, the light part is shrinking: the Moon is waning (moving towards a new Moon). The acronym mnemonic "DOC" represents this ("D" is the waxing Moon; "O" the full moon; and "C" the waning moon). In the Southern hemisphere, this is reversed, and the mnemonic is "COD". A French mnemonic is that the waxing moon at its first "premier" quarter phase looks like a 'p', and the waning moon at its last "dernier" quarter looks like a 'd'. The southern hemisphere equivalent for 'p' and 'd' is that the moon is 'past it', or 'doing it'. One more (Northern hemisphere) mnemonic, which works for most Romance languages, says that the Moon is a liar: it spells "C", as in crescere (Italian for "to grow") when it wanes, and "D" as in decrescere ("decrease") when it waxes. For Polish it is easy to remember that C stands for "cofa się" ("is going back") and D - for "dopełnia się" ("is filling up"). In German, one mnemonic uses the cursive forms of the capital letters A for "abnehmend" (waning) and Z for "zunehmend" (waxing). In Russia, the 'C' stands for "Стареющая" or "[a moon] becoming old", while a line is added to the waning crescent to form 'P', which stands for "Рождающаяся" or "[a moon] getting born" Lunar phase calculation <math>phase=fraction(0.20439731+t*0.03386319269) \,</math>, where t = [UT] - [12AM, January 1, 2001], days such that new moon=.0, first quarter=.25, full moon=.5, last quarter=.75 or a C program.
