First Quarter in Cancer

First Quarter on . The illuminated surface of the moon is 54% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 29 March 2023 at 02:32 UTC.

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 ♋ Cancer

Moon is passing about ∠13° of ♋ Cancer tropical zodiac sector.

Pink Moon after 7 days

Next Full Moon is the Pink Moon of April 2023 after 7 days on 6 April 2023 at 04:35.

Neap tide

There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

Apparent angular diameter ∠1778"

Lunar disc appears visually 7.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1778" and ∠1922".

Lunation 287 / 1240

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 287 of Meeus index or 1240 from Brown series.

Synodic month length 29.45 days

The length of this lunation is 29 days, 10 hours and 49 minutes and it is 52 minutes shorter 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 shorter than mean

The length of the current synodic month is 1 hour and 55 minutes shorter than the mean synodic month length. It is 4 hours and 14 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠34.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠34.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠59.2°.

Moon before apogee

9 days since point of perigee on 19 March 2023 at 15:16 in ♒ Aquarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next day until the Moon reaches the point of next apogee on 31 March 2023 at 11:18 in ♌ Leo.

Distance to Moon 403 099 km

The Moon is 403 099 km (250 474 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 921 km (251 606 mi).

Moon after ascending node

5 days after ascending node on 24 March 2023 at 02:08 in ♉ Taurus the Moon is positioned north of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from North to South in descending node on 7 April 2023 at 13:51 in ♎ Libra.

Moon after northern standstill

1 day since the last northern standstill on 28 March 2023 at 21:29 in ♊ Gemini when the Moon has reached North declination of ∠27.898° the lunar orbit is extending southward over the next 13 days to face maximum declination of ∠-27.947° at the point of next southern standstill on 12 April 2023 at 03:15 in ♑ Capricorn.

Draconic month

5 days since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 7 days

In 7 days on 6 April 2023 at 04:35 in ♎ Libra the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
