First Quarter in Cancer

First Quarter on . The illuminated surface of the moon is 56% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 16 March 2073 at 22:44 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 is entering ♋ Cancer

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

Worm Moon after 6 days

Next Full Moon is the Worm Moon of March 2073 after 6 days on 23 March 2073 at 17:17.

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 ∠1874"

Lunar disc appears visually 2.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1874" and ∠1928".

Lunation 905 / 1858

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 905 of Meeus index or 1858 from Brown series.

Synodic month length 29.75 days

The length of this lunation is 29 days, 17 hours and 58 minutes and it is 1 hour and 57 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 longer than mean

The length of the current synodic month is 5 hours and 14 minutes longer than the mean synodic month length. It is 1 hour and 49 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠168.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠168.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠192.2°.

Moon before perigee

7 days since point of apogee on 10 March 2073 at 03:57 in ♈ Aries the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next perigee on 23 March 2073 at 16:57 in ♍ Virgo.

Distance to Moon 382 571 km

The Moon is 382 571 km (237 719 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 356 721 km (221 656 mi).

Moon before ascending node

10 days after descending node on 7 March 2073 at 07:16 in ♓ Pisces the Moon is positioned south of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from South to North in ascending node on 21 March 2073 at 12:15 in ♍ Virgo.

Moon at northern standstill

At 17:57 the Moon is meeting its standstill point to reach North declination of ∠19.057°. Over the upcoming 12 days the lunar orbit is going to tilt southward to face maximum declination of ∠-19.120° at the point of next southern standstill in ♑ Capricorn on 30 March 2073 at 05:47.

Draconic month

23 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 6 days

In 6 days on 23 March 2073 at 17:17 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.
