Waning Gibbous in Sagittarius

Waning Gibbous on . The illuminated surface of the moon is 81% and getting smaller. The lunar cycle is 19 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 ∠1° of ♐ Sagittarius tropical zodiac sector and will enter ♑ Capricorn later.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 23 April 2081 at 10:20.

Pink Moon before 4 days

Next Full Moon is the Flower Moon of May 2081 after 25 days on 22 May 2081 at 20:26.

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 ∠1825"

Lunar disc appears visually 4.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1825" and ∠1906".

Lunation 1005 / 1958

The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1005 of Meeus index or 1958 from Brown series.

Synodic month length 29.58 days

The length of this lunation is 29 days, 13 hours and 54 minutes and it is 3 hours and 1 minute 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 1 hour and 10 minutes longer than the mean synodic month length. It is 5 hours and 53 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠231.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠231.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠265.8°.

Moon before apogee

6 days since point of perigee on 20 April 2081 at 18:04 in ♍ Virgo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next apogee on 2 May 2081 at 14:12 in ♒ Aquarius.

Distance to Moon 392 803 km

The Moon is 392 803 km (244 076 mi) away from Earth and getting further over the next 5 days until the point apogee when Earth-Moon distance is going to be 404 484 km (251 335 mi).

Moon after descending node

6 days after descending node on 20 April 2081 at 16:02 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 6 days until the lunar crosses the ecliptic again from South to North in ascending node on 4 May 2081 at 10:34 in ♓ Pisces.

Moon at southern standstill

At 11:19 the Moon is meeting its standstill point to reach South declination of ∠-28.521°. Over the upcoming 14 days the lunar orbit is going to tilt northward to face maximum declination of ∠28.437° at the point of next northern standstill in ♊ Gemini on 11 May 2081 at 21:38.

Draconic month

20 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 11 days

In 11 days on 8 May 2081 at 22:09 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.
