First Quarter in Cancer

First Quarter on . The illuminated surface of the moon is 52% and growing larger. The lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 28 March 2091 at 06:31 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 ∠11° of ♋ Cancer tropical zodiac sector.

Pink Moon after 6 days

Next Full Moon is the Pink Moon of April 2091 after 6 days on 4 April 2091 at 01:31.

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 ∠1861"

Lunar disc appears visually 3.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1861" and ∠1922".

Lunation 1128 / 2081

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 1128 of Meeus index or 2081 from Brown series.

Synodic month length 29.73 days

The length of this lunation is 29 days, 17 hours and 34 minutes and it is 1 hour and 47 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 4 hours and 50 minutes longer than the mean synodic month length. It is 2 hours and 13 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠165.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠165.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠189.5°.

Moon before perigee

6 days since point of apogee on 21 March 2091 at 17:48 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 4 April 2091 at 03:26 in ♎ Libra.

Distance to Moon 385 188 km

The Moon is 385 188 km (239 345 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 356 783 km (221 695 mi).

Moon before ascending node

9 days after descending node on 18 March 2091 at 15:30 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 1 April 2091 at 21:03 in ♍ Virgo.

Moon at northern standstill

At 00:55 the Moon is meeting its standstill point to reach North declination of ∠18.531°. Over the upcoming 12 days the lunar orbit is going to tilt southward to face maximum declination of ∠-18.596° at the point of next southern standstill in ♐ Sagittarius on 9 April 2091 at 13:20.

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 4 April 2091 at 01:31 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.
