![]() Every two weeks, we have to look in the opposite direction to see the Moon, and the ground beneath our feet is then tilted the opposite way as well. The lunar cycle takes close to four weeks so seven days is a quarter of the way through the cycle, first quarter, even though the Moon is half lit. The tilted ramp works the same as the tilted “platform” of the Earth beneath our feet. If you turn around, the horizon appears to tilt the opposite way. New Moon: The Moon is between the Sun and Earth. In this phase the Moon’s illumination is growing smaller each day until the New Moon. This phase is best viewed just before the sunrise in the western sky. ![]() The Predictions are accurate to about one minute, and given in South African Standard Time. Illumination: 0 Position in space: the Moon is between the Sun and Earth If the Moon’s path crosses the plane of Earth's orbit around the Sun (the ecliptic) while the Sun, Moon, and Earth are aligned at New Moon, a solar eclipse happens somewhere in the world. Moon Phase: SeptemOn this day the Moon was in a Waning Crescent phase. The Moon spends the extra 2.2 days catching up. Usually, each season has three months and three New Moons. In front of you, the horizon looks higher on the right and lower on the left. The following list gives the times of phases of the Moon for 2021. The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days. We divide a year into four seasons spring, summer, fall (autumn), and winter. Earth has a tilt of 23.5 degrees on its axis, which means that when we observe the Moon from Earth, it’s a little like we’re standing sideways on a ramp. The tilt of the Moon’s orbit contributes to this, but it’s mostly due to the tilt of our Earth. We call this motion “libration in latitude.”įinally, the Moon appears to tilt back and forth like a metronome. The 5 degree tilt of the Moon’s orbit also causes it to appear to nod, as though it were saying “yes.” The tilt sometimes brings the Moon above Earth’s northern hemisphere, and sometimes below Earth’s southern hemisphere, allowing us to see slightly more of the northern or southern hemispheres of the Moon. When is the full moon Calendar dates for 2023 September 29, Harvest Moon, 5:57 a.m. We call this motion “libration in longitude.” NASA says this is due to a 'wobble' in the moon's orbit working in tandem with climate. is facing rapidly increasing high tide floods. When the Moon is farthest from Earth and orbiting at its slowest, its rotation gets a little ahead, and we see a bit more of its western side. J/ 3:13 PM / CBS News Every coast in the U.S. When the Moon is at its closest to Earth and moving most quickly along its orbital path, the Moon itself doesn’t rotate quite fast enough to keep entirely the same side facing us, and we get to see a little more of the eastern side of the Moon. This visualization of the Moons phases throughout the year 2021 also shows lunar libration, the apparent rolling motion that changes our view of the Moon. The full moon on 24 th July 2021 is the first of two full moons in Aquarius making the second (22 nd August) an auspicious blue moon. ![]() ![]() A new study predicts that high tide flooding in coastal areas could. ![]() The Moon’s rate of rotation around its own axis, though, always stays the same. 24th July 2021 22nd August 2021 Blue Moon Cycle in Aquarius All dates are UT so may vary in your time zone.

Hover over events for more details.Because the Moon's orbit is not perfectly circular, its distance from Earth and its speed in orbit both change slightly throughout the month. Current lunation cycle is highlighted yellow. Dates are based on the Gregorian calendar. Time is adjusted for DST when applicable.
