Waning Gibbous in Aquarius

Waning Gibbous on . The illuminated surface of the moon is 98% 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 ♒ Aquarius

Moon is passing about ∠15° of ♒ Aquarius tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 21 July 2005 at 11:00.

Buck Moon before 1 day

Next Full Moon is the Sturgeon Moon of August 2005 after 28 days on 19 August 2005 at 17:53.

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 4.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1889".

Lunation 68 / 1021

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 68 of Meeus index or 1021 from Brown series.

Synodic month length 29.63 days

The length of this lunation is 29 days, 15 hours and 2 minutes and it is 39 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 2 hours and 18 minutes longer than the mean synodic month length. It is 4 hours and 45 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠158.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠158.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠181.9°.

Moon after perigee

1 day since point of perigee on 21 July 2005 at 19:44 in ♑ Capricorn the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 13 days until the Moon reaches the point of next apogee on 4 August 2005 at 21:49 in ♌ Leo.

Distance to Moon 363 369 km

The Moon is 363 369 km (225 787 mi) away from Earth and getting further over the next 13 days until the point apogee when Earth-Moon distance is going to be 406 631 km (252 669 mi).

Moon before ascending node

8 days after descending node on 14 July 2005 at 06:35 in ♎ Libra the Moon is positioned south of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from South to North in ascending node on 26 July 2005 at 17:58 in ♈ Aries.

Moon after southern standstill

2 days since the last southern standstill on 19 July 2005 at 17:52 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.265° the lunar orbit is extending northward over the next 10 days to face maximum declination of ∠28.311° at the point of next northern standstill on 1 August 2005 at 18:06 in ♊ Gemini.

Draconic month

22 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 13 days

In 13 days on 5 August 2005 at 03:05 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.
