Waning Gibbous in Sagittarius

Waning Gibbous on . Illuminated surface of the Moon is 86% 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 passing about ∠19° of ♐ Sagittarius tropical zodiac sector.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 20 April 2008 at 10:25.

Pink Moon before 4 days

Next Full Moon is the Flower Moon of May 2008 after 25 days on 20 May 2008 at 02:11.

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 ∠1772"

Lunar disc appears visually 7.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1772" and ∠1907".

Lunation 102 / 1055

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 102 of Meeus index or 1055 from Brown series.

Synodic month length 29.35 days

The length of this lunation is 29 days, 8 hours and 23 minutes and it is 1 hour and 19 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 shorter than mean

The length of the current synodic month is 4 hours and 21 minutes shorter than the mean synodic month length. It is 1 hour and 48 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠332.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠332.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠349.4°.

Moon after apogee

1 day since point of apogee on 23 April 2008 at 09:34 in ♐ Sagittarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next perigee on 6 May 2008 at 03:22 in ♉ Taurus.

Distance to Moon 404 533 km

The Moon is 404 533 km (251 365 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 357 772 km (222 309 mi).

Moon before ascending node

9 days after descending node on 15 April 2008 at 05:48 in ♌ Leo the Moon is positioned south of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from South to North in ascending node on 29 April 2008 at 20:07 in ♒ Aquarius.

Moon at southern standstill

At 22:36 the Moon is meeting its standstill point to reach South declination of ∠-27.695°. Over the upcoming 13 days the lunar orbit is going to tilt northward to face maximum declination of ∠27.625° at the point of next northern standstill in ♊ Gemini on 8 May 2008 at 01:51.

Draconic month

21 days since the beginning of this draconic month in ♒ Aquarius the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 11 days

In 11 days on 5 May 2008 at 12:18 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.
