Waning Gibbous in Aries

Waning Gibbous on . The illuminated surface of the moon is 99% and getting smaller. The lunar cycle is 15 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 is entering ♈ Aries

Moon is passing first ∠2° of ♈ Aries tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 11 September 2068 at 17:19.

Harvest Moon before 1 day

Next Full Moon is the Hunter Moon of October 2068 after 28 days on 11 October 2068 at 01:39.

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 ∠1973"

Lunar disc appears visually 3.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1907".

Lunation 849 / 1802

The Moon is 15 days old and navigating from the middle to the last part of the current synodic month. This is lunation 849 of Meeus index or 1802 from Brown series.

Synodic month length 29.68 days

The length of this lunation is 29 days, 16 hours and 20 minutes and it is 1 hour and 9 minutes shorter 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 3 hours and 36 minutes longer than the mean synodic month length. It is 3 hours and 27 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠160.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠160.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠183.9°.

Moon at perigee

Moon is at perigee at 00:17 about 13 days since last apogee on 29 August 2068 at 20:38 in ♍ Virgo 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 26 September 2068 at 00:00 in ♎ Libra.

Distance to Moon 356 950 km

This perigee Moon is 356 950 km (221 798 mi) away from Earth. It is 5 558 km closer than the mean perigee distance, but it is still 13 406 km further than the closest perigee of 21st century.

Moon before descending node

8 days after ascending node on 3 September 2068 at 12:48 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from North to South in descending node on 16 September 2068 at 02:30 in ♉ Taurus.

Moon before northern standstill

7 days since the last southern standstill on 5 September 2068 at 09:10 in ♐ Sagittarius when the Moon has reached South declination of ∠-20.990° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠20.889° at the point of next northern standstill on 17 September 2068 at 21:08 in ♊ Gemini.

Draconic month

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

Syzygy in 13 days

In 13 days on 26 September 2068 at 10:48 in ♎ Libra 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.
