Waning Gibbous in Sagittarius

Waning Gibbous on . Illuminated surface of the Moon is 84% and getting smaller. Lunar cycle is 18 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.

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 27 April 2021 at 03:31.

Pink Moon before 3 days

Next Full Moon is the Flower Moon of May 2021 after 25 days on 26 May 2021 at 11:14.

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 ∠1954"

Lunar disc appears visually 2.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1954" and ∠1904".

Lunation 263 / 1216

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 263 of Meeus index or 1216 from Brown series.

Synodic month length 29.69 days

The length of this lunation is 29 days, 16 hours and 29 minutes and it is 36 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2021. 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 3 hours and 45 minutes longer than the mean synodic month length. It is 3 hours and 18 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠154.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠154.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠178.9°.

Moon after perigee

2 days since point of perigee on 27 April 2021 at 15:24 in ♏ Scorpio the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next apogee on 11 May 2021 at 21:54 in ♉ Taurus.

Distance to Moon 366 765 km

The Moon is 366 765 km (227 897 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 406 512 km (252 595 mi).

Moon after descending node

1 day after descending node on 29 April 2021 at 09:18 in ♐ Sagittarius the Moon is positioned south of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from South to North in ascending node on 13 May 2021 at 10:29 in ♊ Gemini.

Moon before southern standstill

11 days since the last northern standstill on 18 April 2021 at 16:02 in ♋ Cancer when the Moon has reached North declination of ∠25.532° the lunar orbit is extending southward over the next day to face maximum declination of ∠-25.591° at the point of next southern standstill on 1 May 2021 at 09:37 in ♑ Capricorn.

Draconic month

14 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 11 days

In 11 days on 11 May 2021 at 19:00 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.
