Waning Gibbous in Sagittarius

Waning Gibbous on . The illuminated surface of the moon is 93% and getting smaller. The lunar cycle is 17 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 passing about ∠6° of ♐ Sagittarius tropical zodiac sector.

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 24 April 2100 at 09:43.

Pink Moon before 2 days

Next Full Moon is the Flower Moon of May 2100 after 27 days on 23 May 2100 at 17:25.

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 ∠1949"

Lunar disc appears visually 2.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1949" and ∠1906".

Lunation 1240 / 2193

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1240 of Meeus index or 2193 from Brown series.

Synodic month length 29.69 days

The length of this lunation is 29 days, 16 hours and 37 minutes and it is 1 hour and 59 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 3 hours and 53 minutes longer than the mean synodic month length. It is 3 hours and 10 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠176.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠176.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠200.1°.

Moon after perigee

2 days since point of perigee on 24 April 2100 at 02:13 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 10 days until the Moon reaches the point of next apogee on 7 May 2100 at 05:13 in ♈ Aries.

Distance to Moon 367 728 km

The Moon is 367 728 km (228 496 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 406 376 km (252 510 mi).

Moon after descending node

5 days after descending node on 21 April 2100 at 05:33 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from South to North in ascending node on 4 May 2100 at 01:19 in ♓ Pisces.

Moon before southern standstill

11 days since the last northern standstill on 15 April 2100 at 08:21 in ♊ Gemini when the Moon has reached North declination of ∠28.446° the lunar orbit is extending southward over the next day to face maximum declination of ∠-28.374° at the point of next southern standstill on 28 April 2100 at 00:08 in ♑ Capricorn.

Draconic month

19 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 12 days

In 12 days on 9 May 2100 at 08:54 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.
