Waning Gibbous in Aries

Waning Gibbous on . The illuminated surface of the moon is 90% and getting smaller. The lunar cycle is 18 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 ∠1° of ♈ Aries tropical zodiac sector.

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 12 August 2098 at 01:44.

Sturgeon Moon before 3 days

Next Full Moon is the Harvest Moon of September 2098 after 26 days on 10 September 2098 at 17:33.

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 ∠1796"

Lunar disc appears visually 5.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1796" and ∠1895".

Lunation 1219 / 2172

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1219 of Meeus index or 2172 from Brown series.

Synodic month length 29.29 days

The length of this lunation is 29 days, 7 hours and 2 minutes and it is 1 hour and 22 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 5 hours and 42 minutes shorter than the mean synodic month length. It is 27 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠355.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠355.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠10.1°.

Moon after apogee

3 days since point of apogee on 11 August 2098 at 14:55 in ♒ Aquarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next perigee on 26 August 2098 at 01:27 in ♌ Leo.

Distance to Moon 399 008 km

The Moon is 399 008 km (247 932 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 357 798 km (222 325 mi).

Moon before ascending node

13 days after descending node on 2 August 2098 at 04:55 in ♎ Libra the Moon is positioned south of the ecliptic over the following day until the lunar crosses the ecliptic again from South to North in ascending node on 16 August 2098 at 17:55 in ♈ Aries.

Moon before northern standstill

7 days since the last southern standstill on 8 August 2098 at 03:03 in ♑ Capricorn when the Moon has reached South declination of ∠-28.295° the lunar orbit is extending northward over the next 7 days to face maximum declination of ∠28.393° at the point of next northern standstill on 22 August 2098 at 13:44 in ♊ Gemini.

Draconic month

25 days since the beginning of this draconic month in ♈ Aries the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 11 days

In 11 days on 26 August 2098 at 15:52 in ♌ Leo 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.
