Sunlit Tides' title='Sunlit Tides' />The moon was near its greatest northern ecliptic latitude, so the southern craters are especially prominent. A full moon is the lunar phase that occurs when the Moon is completely illuminated as seen from Earth. This occurs when Earth is located directly between the Sun and the Moon more exactly, when the ecliptic longitudes of the Sun and Moon differ by 1. This means that the hemisphere of the Moon that is facing Earth the near side is almost fully illuminated by the Sun and appears round while the far side is almost completely unlit. A full moon occurs every once a month. When the full moon moves into Earths shadow, a lunar eclipse occurs, and all or part of the Moons face may appear reddish due to the Rayleigh scattering of blue light in Earths atmosphere. Lunar eclipses can occur only at full moon, where the Moons orbit allows it to pass through Earths shadow. Sunlit Tides' title='Sunlit Tides' />Ocean Printouts and Activities.

Lunar eclipses do not occur every month because the Moon usually passes above or below Earths shadow, which is mostly restricted to the ecliptic plane. Lunar eclipses can occur only when the full moon occurs near the two nodes of the orbit, either the ascending or descending node. This causes eclipses to occur about every 6 months, and often 2 weeks before or after a solar eclipse at new moon at the opposite node. The time interval between similar lunar phasesthe synodic monthaverages about 2. Therefore, in those lunar calendars in which each month begins on the new moon, the full moon falls on either the 1. Because calendar months have a whole number of days, lunar months may be either 2. CharacteristicseditA full moon is often thought of as an event of a full nights duration. This is somewhat misleading because its phase seen from Earth continuously waxes or wanes though much too slowly to notice in real time with the naked eye. Its maximum illumination occurs at the moment waxing has stopped. For any given location, about half of these maximum full moons may be visible, while the other half occurs during the day, when the full moon is below the horizon. Many almanacs list full moons not only by date, but also by their exact time, usually in Coordinated Universal Time UTC. Typical monthly calendars that include lunar phases may be offset by one day when used in a different time zone. Full moon is generally a suboptimal time to conduct astronomical observations because the bright sunlight reflected by the Moon then outshines the apparently dimmer stars. On 1. 2 December 2.

See New moon for an explanation of the formula and its parameters. The age and apparent size of the full moon vary in a cycle of just under 1. In folklore and traditioneditFull moons are traditionally associated with temporal insomnia inability to sleep, insanity hence the terms lunacy and lunatic and various magical phenomena such as lycanthropy. Psychologists, however, have found that there is no strong evidence for effects on human behavior around the time of a full moon. They find that studies are generally not consistent, with some showing a positive effect and others showing a negative effect. In one instance, the 2. December 2. 00. 0 issue of the British Medical Journal published two studies on dog bite admission to hospitals in England and Australia. The study of the Bradford Royal Infirmary found that dog bites were twice as common during a full moon, whereas the study conducted by the public hospitals in Australia found that they were less likely. All this is relevant to canine rather than human behavior. Full moon nameseditHistorically, month names are names of moons lunations, not necessarily full moons in lunisolar calendars. Since the introduction of the solar Julian calendar in the Roman Empire, and later the Gregorian calendar worldwide, people no longer perceive month names as moon names. The traditional Old English month names were equated with the names of the Julian calendar from an early time soon after Christianization, according to the testimony of Bede ca. AD 7. 00. Some full moons have developed new names in modern times, e. Harvest and hunters moonsedit. A harvest moon. Its orange color is due to its closeness to the horizon, rather than being unique to harvest moons. The harvest moon and hunters moon are traditional terms for the full moons occurring during late summer and in the autumn, in the northern hemisphere usually in September and October respectively. The harvest moon is the full moon closest to the autumnal equinox 2. September, coming anywhere from two weeks before to two weeks after that date. The hunters moon is the full moon following it. The names are recorded from the early 1. The Oxford English Dictionary entry for harvest moon cites a 1. The British Apollo, where the term is attributed to the country people The Country People call this the Hunters Moon. The names became traditional in American folklore, where they are now often popularly attributed to the Native Americans. The Feast of the Hunters Moon is a yearly festival in West Lafayette, Indiana, held in late September or early October each year since 1. In 2. 01. 0, the Harvest moon occurred on the night of equinox itself some 5 12 hours after the point of equinox for the first time since 1. All full moons rise around the time of sunset. Because the moon moves eastward among the stars faster than the sun its meridian passage is delayed, causing it to rise later each day on average by about 5. The harvest moon and hunters moon are unique because the time difference between moonrises on successive evenings is much shorter than average. The moon rises approximately 3. N or S latitude. This is because a full moon in September appears to move not straight east but north east in the sky. Thus, there is no long period of darkness between sunset and moonrise for several days following the actual date of the full moon. Farmers AlmanacseditThe Maine Farmers Almanac from c.

But why The good way to understand the phases of the moon is to examine an earth moon sun diagram Moon. Connection. com All Rights Reserved.

Please contact me for high resolution version available for small license fee. Diagram Explanation. The illustration may look a little complex at first, but its easy to explain. Sunlight is shown coming in from the right. The earth, of course, is at the center of the diagram. The moon is shown at 8 key stages during its revolution around the earth. The moon phase name is shown alongside the image. The dotted line from the earth to the moon represents your line of sight when looking at the moon. The large moon image shows what you would see at that point in the cycle. For the waning gibbous, third quarter, and waning crescent phases you have to mentally turn yourself upside down when imagining the line of sight. When you do this, youll see that the illuminated portion is on your left, just as you see in the large image. One important thing to notice is that exactly one half of the moon is always illuminated by the sun. Of course that is perfectly logical, but you need to visualize it in order to understand the phases. At certain times we see both the sunlit portion and the shadowed portion and that creates the various moon phase shapes we are all familiar with. Also note that the shadowed part of the moon is invisible to the naked eye in the diagram above, it is only shown for clarification purposes. Finally, please realize this diagram is only meant to demonstrate how the phases work the small inner moons in the diagram do not show the fact that the same side of the moon always faces Earth. So the basic explanation is that the lunar phases are created by changing angles relative positions of the earth, the moon and the sun, as the moon orbits the earth. If youd like to examine the phases of the moon more closely, via computer software, you may be interested in this moon phases calendar software. Moon Phases Simplified. Its probably easiest to understand the moon cycle in this order new moon and full moon, first quarter and third quarter, and the phases in between. As shown in the above diagram, the new moon occurs when the moon is positioned between the earth and sun. The three objects are in approximate alignment why approximate is explained below. The entire illuminated portion of the moon is on the back side of the moon, the half that we cannot see. At a full moon, the earth, moon, and sun are in approximate alignment, just as the new moon, but the moon is on the opposite side of the earth, so the entire sunlit part of the moon is facing us. The shadowed portion is entirely hidden from view. The first quarter and third quarter moons both often called a half moon, happen when the moon is at a 9. So we are seeing exactly half of the moon illuminated and half in shadow. Once you understand those four key moon phases, the phases between should be fairly easy to visualize, as the illuminated portion gradually transitions between them. An easy way to remember and understand those between lunar phase names is by breaking out and defining 4 words crescent, gibbous, waxing, and waning. The word crescent refers to the phases where the moon is less than half illuminated. The word gibbous refers to phases where the moon is more than half illuminated. Waxing essentially means growing or expanding in illumination, and waning means shrinking or decreasing in illumination. Biggies Best Hits on this page. Thus you can simply combine the two words to create the phase name, as follows After the new moon, the sunlit portion is increasing, but less than half, so it is waxing crescent. After the first quarter, the sunlit portion is still increasing, but now it is more than half, so it is waxing gibbous. After the full moon maximum illumination, the light continually decreases. So the waning gibbous phase occurs next. Following the third quarter is the waning crescent, which wanes until the light is completely gone a new moon. The Moons Orbit. You may have personally observed that the moon goes through a complete moon phases cycle in about one month. Thats true, but its not exactly one month. The synodic period or lunation is exactly 2. Its the time required for the moon to move to the same position same phase as seen by an observer on earth. If you were to view the moon cycling the earth from outside our solar system the viewpoint of the stars, the time required is 2. This figure is called the sidereal period or orbital period. Why is the synodic period different from the sidereal period The short answer is because on earth, we are viewing the moon from a moving platform during the moon cycle, the earth has moved approximately one month along its year long orbit around the sun, altering our angle of view with respect to the moon, and thus altering the phase. The earths orbital direction is such that it lengthens the period for earthbound observers. Although the synodic and sidereal periods are exact numbers, the moon phase cant be precisely calculated by simple division of days because the moons motion orbital speed and position is affected and perturbed by various forces of different strengths. Hence, complex equations are used to determine the exact position and phase of the moon at any given point in time. Also, looking at the diagram and imagining it to scale, you may have wondered why, at a new moon, the moon doesnt block the sun, and at a full moon, why the earth doesnt block sunlight from reaching the moon. The reason is because the moons orbit about the earth is about 5 degrees off from the earth sun orbital plane. However, at special times during the year, the earth, moon, and sun do in fact line up. When the moon blocks the sun or a part of it, its called a solar eclipse, and it can only happen during the new moon phase. When the earth casts a shadow on the moon, its called a lunar eclipse, and can only happen during the full moon phase. Roughly 4 to 7 eclipses happen in any given year, but most of them minor or partial eclipses. Major lunar or solar eclipses are relatively uncommon. Moon Software.
