Waning Gibbous in Sagittarius

Waning Gibbous on . Illuminated surface of the Moon is 96% and getting smaller. Lunar cycle is 16 days old.

Moonrise and moonset

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.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♐ Sagittarius

Moon is leaving the last ∠3° of ♐ Sagittarius tropical zodiac sector and will enter ♑ Capricorn later.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 23 May 2005 at 20:18.

Flower Moon before 1 day

Next Full Moon is the Strawberry Moon of June 2005 after 27 days on 22 June 2005 at 04:14.

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 ∠1953"

Lunar disc appears visually 3.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1953" and ∠1894".

Lunation 66 / 1019

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 66 of Meeus index or 1019 from Brown series.

Synodic month length 29.55 days

The length of this lunation is 29 days, 13 hours and 10 minutes and it is 57 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 longer than mean

The length of the current synodic month is 26 minutes longer than the mean synodic month length. It is 6 hours and 37 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠96.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠96.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠131.2°.

Moon before perigee

10 days since point of apogee on 14 May 2005 at 13:41 in ♋ Cancer the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next day until the Moon reaches the point of next perigee on 26 May 2005 at 10:43 in ♑ Capricorn.

Distance to Moon 367 035 km

The Moon is 367 035 km (228 065 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 364 241 km (226 329 mi).

Moon after descending node

4 days after descending node on 20 May 2005 at 22:02 in ♎ Libra 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 2 June 2005 at 15:14 in ♈ Aries.

Moon at southern standstill

At 23:03 the Moon is meeting its standstill point to reach South declination of ∠-28.270°. Over the upcoming 13 days the lunar orbit is going to tilt northward to face maximum declination of ∠28.224° at the point of next northern standstill in ♋ Cancer on 8 June 2005 at 07:36.

Draconic month

19 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 12 days

In 12 days on 6 June 2005 at 21:55 in ♊ Gemini 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.
