First Quarter in Cancer

First Quarter on . Illuminated surface of the Moon is 55% and growing larger. Lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 18 March 2043 at 01:03 UTC.

Moonrise and moonset

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

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon is entering ♋ Cancer

Moon is passing first ∠4° of ♋ Cancer tropical zodiac sector.

Worm Moon after 7 days

Next Full Moon is the Worm Moon of March 2043 after 7 days on 25 March 2043 at 14:26.

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 ∠1934"

Lunar disc appears visually 0.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1934" and ∠1927".

Lunation 534 / 1487

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 534 of Meeus index or 1487 from Brown series.

Synodic month length 29.41 days

The length of this lunation is 29 days, 9 hours and 57 minutes and it is 1 hour and 42 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length shorter than mean

The length of the current synodic month is 2 hours and 47 minutes shorter than the mean synodic month length. It is 3 hours and 22 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠327.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠327.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠345.1°.

Moon after perigee

5 days since point of perigee on 13 March 2043 at 09:10 in ♈ Aries the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next apogee on 29 March 2043 at 05:28 in ♏ Scorpio.

Distance to Moon 370 620 km

The Moon is 370 620 km (230 293 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 405 650 km (252 059 mi).

Moon after ascending node

5 days after ascending node on 12 March 2043 at 14:36 in ♈ Aries the Moon is positioned north of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from North to South in descending node on 25 March 2043 at 21:58 in ♎ Libra.

Moon at northern standstill

At 08:45 the Moon is meeting its standstill point to reach North declination of ∠28.648°. Over the upcoming 14 days the lunar orbit is going to tilt southward to face maximum declination of ∠-28.660° at the point of next southern standstill in ♐ Sagittarius on 1 April 2043 at 21:04.

Draconic month

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

Syzygy in 7 days

In 7 days on 25 March 2043 at 14:26 in ♍ Virgo 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.
