Waning Crescent in Aries

Waning Crescent on . The illuminated surface of the moon is 36% and getting smaller. The lunar cycle is 23 days old.

Moonrise and moonset

The moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon phase and lunation details

Moon in ♈ Aries

Moon is leaving the last ∠4° of ♈ Aries tropical zodiac sector and will enter ♉ Taurus later.

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 1 July 2051 at 07:15.

Buck Moon after 21 days

Next Full Moon is the Buck Moon of July 2051 after 21 days on 23 July 2051 at 16:36.

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 ∠1972"

Lunar disc appears visually 4.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1887".

Lunation 636 / 1589

The Moon is 23 days old and navigating from the second to the final part of the current synodic month. This is lunation 636 of Meeus index or 1589 from Brown series.

Synodic month length 29.38 days

The length of this lunation is 29 days, 9 hours and 13 minutes and it is 1 hour and 43 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 3 hours and 31 minutes shorter than the mean synodic month length. It is 2 hours and 38 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠43.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠43.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠70.2°.

Moon at perigee

Moon is at perigee at 20:59 about 14 days since last apogee on 17 June 2051 at 22:14 in ♎ Libra the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 13 days until point of next apogee on 15 July 2051 at 16:49 in ♎ Libra.

Distance to Moon 369 221 km

This perigee Moon is 369 221 km (229 423 mi) away from Earth. This is the year's farthest perigee of 2051. It is 6 713 km closer than the mean perigee distance, but it is still 1 135 km further than the closest perigee of 21st century.

Moon in descending node

Moon is in descending node in ♈ Aries at 17:54 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 13 days until Moon's next ascending node later on 16 July 2051 at 09:35 in ♎ Libra.

Moon before northern standstill

9 days since the last southern standstill on 23 June 2051 at 11:15 in ♐ Sagittarius when the Moon has reached South declination of ∠-19.227° the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠19.198° at the point of next northern standstill on 6 July 2051 at 11:58 in ♊ Gemini.

Draconic month

13 days since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the middle to the last part of the lunar cycle.

Syzygy in 5 days

In 5 days on 8 July 2051 at 04:09 in ♋ Cancer the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
