First Quarter in Gemini

First Quarter on . The illuminated surface of the moon is 48% and growing larger. The lunar cycle is 7 days young.

* The exact date and time of this phase is on at : .

Moonrise and moonset

The moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon phase and lunation details

Moon in ♊ Gemini

Moon is passing about ∠19° of ♊ Gemini tropical zodiac sector.

Moon after 1 day

Next Full Moon is the Moon of after 1 day on at :.

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Apparent angular diameter ∠1940"

Lunar disc appears visually 0.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1940" and ∠1931".

Lunation -953 /

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation -953 of Meeus index or from Brown series.

Synodic month length 0 days

The length of this lunation is days, 1 hour and 1 minute and it is longer than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length same as the mean

The length of the current synodic month is equal to the mean synodic month length. It is %hours_to_shortest% and %minutes_to_shortest% longer than the 21st century's shortest and %hours_to_longest% and %minutes_to_longest% shorter than the 21st century's longest synodic months.

Lunar orbit details for

True anomaly ∠0°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠0° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠0°.

Moon before perigee

42803 days since point of apogee on at : in &#; the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next day until the Moon reaches the point of next perigee on at : in &#; .

Distance to Moon 369 557 km

The Moon is 369 557 km (229 632 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 0 km (0 mi).

Moon before descending node

42803 days after descending node on at : in &#; the Moon is positioned south of the ecliptic over the following day until the lunar crosses the ecliptic again from South to North in ascending node on at : in &#; .

Moon before northern standstill

42803 days since the last southern standstill on at : in &#; when the Moon has reached South declination of ∠° the lunar orbit is extending northward over the next day to face maximum declination of ∠° at the point of next northern standstill on at : in &#; .

Draconic month

42803 days since the beginning of this draconic month in &#; the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 1 day

In 1 day on at : in &#; the Moon is going to be in a geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
