Waning Gibbous in Aries

Waning Gibbous on . The illuminated surface of the moon is 93% and getting smaller. The lunar cycle is 17 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 leaving the last ∠2° of ♈ Aries tropical zodiac sector and will enter ♉ Taurus later.

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 15 September 2092 at 20:33.

Harvest Moon before 2 days

Next Full Moon is the Hunter Moon of October 2092 after 26 days on 15 October 2092 at 10:25.

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 ∠1801"

Lunar disc appears visually 5.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1801" and ∠1910".

Lunation 1146 / 2099

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1146 of Meeus index or 2099 from Brown series.

Synodic month length 29.46 days

The length of this lunation is 29 days, 11 hours and 1 minute and it is 48 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 shorter than mean

The length of the current synodic month is 1 hour and 43 minutes shorter than the mean synodic month length. It is 4 hours and 26 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠282.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠282.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠312.2°.

Moon before apogee

10 days since point of perigee on 8 September 2092 at 07:44 in ♐ Sagittarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 4 days until the Moon reaches the point of next apogee on 22 September 2092 at 14:18 in ♊ Gemini.

Distance to Moon 397 915 km

The Moon is 397 915 km (247 253 mi) away from Earth and getting further over the next 4 days until the point apogee when Earth-Moon distance is going to be 404 407 km (251 287 mi).

Moon after descending node

5 days after descending node on 12 September 2092 at 21:06 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from South to North in ascending node on 27 September 2092 at 04:29 in ♌ Leo.

Moon before northern standstill

8 days since the last southern standstill on 10 September 2092 at 11:11 in ♑ Capricorn when the Moon has reached South declination of ∠-20.164° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠20.251° at the point of next northern standstill on 24 September 2092 at 12:04 in ♋ Cancer.

Draconic month

18 days since the beginning of this draconic month in ♌ Leo the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 12 days

In 12 days on 1 October 2092 at 09:15 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.
