Waning Gibbous in Aquarius

Waning Gibbous on . The illuminated surface of the moon is 66% and getting smaller. The lunar cycle is 20 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.

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon is entering ♒ Aquarius

Moon is passing first ∠2° of ♒ Aquarius tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 4 May 2099 at 17:58.

Flower Moon before 5 days

Next Full Moon is the Strawberry Moon of June 2099 after 23 days on 3 June 2099 at 03:37.

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 ∠1798"

Lunar disc appears visually 5.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1798" and ∠1900".

Lunation 1228 / 2181

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1228 of Meeus index or 2181 from Brown series.

Synodic month length 29.57 days

The length of this lunation is 29 days, 13 hours and 47 minutes and it is 2 hours and 53 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 longer than mean

The length of the current synodic month is 1 hour and 3 minutes longer than the mean synodic month length. It is 6 hours shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠227.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠227.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠261.4°.

Moon before apogee

8 days since point of perigee on 2 May 2099 at 05:55 in ♎ Libra the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next apogee on 14 May 2099 at 02:22 in ♓ Pisces.

Distance to Moon 398 689 km

The Moon is 398 689 km (247 734 mi) away from Earth and getting further over the next 3 days until the point apogee when Earth-Moon distance is going to be 404 556 km (251 379 mi).

Moon before ascending node

8 days after descending node on 2 May 2099 at 00:59 in ♎ Libra the Moon is positioned south of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from South to North in ascending node on 15 May 2099 at 18:40 in ♓ Pisces.

Moon after southern standstill

2 days since the last southern standstill on 8 May 2099 at 02:14 in ♑ Capricorn when the Moon has reached South declination of ∠-28.539° the lunar orbit is extending northward over the next 12 days to face maximum declination of ∠28.471° at the point of next northern standstill on 22 May 2099 at 13:50 in ♊ Gemini.

Draconic month

21 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 9 days

In 9 days on 20 May 2099 at 05:16 in ♉ Taurus 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.
