Waning Gibbous in Sagittarius

Waning Gibbous on . The illuminated surface of the moon is 99% and getting smaller. The lunar cycle is 15 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 ♐ Sagittarius

Moon is leaving the last ∠2° 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 6 June 2077 at 15:07.

Strawberry Moon before 1 day

Next Full Moon is the Buck Moon of July 2077 after 28 days on 6 July 2077 at 01:22.

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 ∠1877"

Lunar disc appears visually 0.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1877" and ∠1890".

Lunation 957 / 1910

The Moon is 15 days old and navigating from the middle to the last part of the current synodic month. This is lunation 957 of Meeus index or 1910 from Brown series.

Synodic month length 29.43 days

The length of this lunation is 29 days, 10 hours and 17 minutes and it is 1 hour and 29 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 2 hours and 27 minutes shorter than the mean synodic month length. It is 3 hours and 42 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠50.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠50.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠80.3°.

Moon before perigee

7 days since point of apogee on 30 May 2077 at 18:38 in ♍ Virgo the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next perigee on 13 June 2077 at 20:17 in ♓ Pisces.

Distance to Moon 381 847 km

The Moon is 381 847 km (237 269 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 369 667 km (229 700 mi).

Moon after descending node

1 day after descending node on 5 June 2077 at 23:08 in ♐ Sagittarius the Moon is positioned south of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from South to North in ascending node on 18 June 2077 at 21:39 in ♊ Gemini.

Moon before southern standstill

13 days since the last northern standstill on 24 May 2077 at 22:23 in ♋ Cancer when the Moon has reached North declination of ∠25.836° the lunar orbit is extending southward over the next day to face maximum declination of ∠-25.830° at the point of next southern standstill on 8 June 2077 at 08:58 in ♑ Capricorn.

Draconic month

15 days since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 13 days

In 13 days on 20 June 2077 at 12:55 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.
