Waning Gibbous in Aries

Waning Gibbous on . The illuminated surface of the moon is 97% and getting smaller. The lunar cycle is 16 days old.

Moonrise and moonset

The moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon phase and lunation details

Moon in ♈ Aries

Moon is passing about ∠8° of ♈ Aries tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 9 September 2033 at 02:20.

Harvest Moon before 1 day

Next Full Moon is the Hunter Moon of October 2033 after 27 days on 8 October 2033 at 10:58.

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 ∠1972"

Lunar disc appears visually 3.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1906".

Lunation 416 / 1369

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 416 of Meeus index or 1369 from Brown series.

Synodic month length 29.67 days

The length of this lunation is 29 days, 16 hours and 1 minute and it is 1 hour and 49 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 longer than mean

The length of the current synodic month is 3 hours and 16 minutes longer than the mean synodic month length. It is 3 hours and 47 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠140.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠140.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠166.6°.

Moon at perigee

Moon is at perigee at 01:49 about 12 days since last apogee on 28 August 2033 at 15:27 in ♎ Libra the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 14 days until point of next apogee on 25 September 2033 at 01:33 in ♎ Libra.

Distance to Moon 358 590 km

This perigee Moon is 358 590 km (222 817 mi) away from Earth. It is 3 918 km closer than the mean perigee distance, but it is still 11 766 km further than the closest perigee of 21st century.

Moon in descending node

Moon is in descending node in ♈ Aries at 19:07 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 14 days until Moon's next ascending node later on 24 September 2033 at 12:46 in ♎ Libra.

Moon before northern standstill

7 days since the last southern standstill on 3 September 2033 at 09:54 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.364° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠18.313° at the point of next northern standstill on 15 September 2033 at 23:39 in ♊ Gemini.

Draconic month

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

Syzygy in 13 days

In 13 days on 23 September 2033 at 13:40 in ♍ Virgo 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.
