Waning Gibbous in Sagittarius

Waning Gibbous on . Illuminated surface of the Moon is 92% and getting smaller. Lunar cycle is 17 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 ∠21° of ♐ Sagittarius tropical zodiac sector.

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 6 May 2012 at 03:35.

Flower Moon before 2 days

Next Full Moon is the Strawberry Moon of June 2012 after 26 days on 4 June 2012 at 11:12.

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 ∠1955"

Lunar disc appears visually 2.8% wider than solar disc. Moon and Sun apparent angular diameters are ∠1955" and ∠1901".

Lunation 152 / 1105

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 152 of Meeus index or 1105 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 1 hour and 14 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 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 ∠168.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠168.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠191.8°.

Moon after perigee

2 days since point of perigee on 6 May 2012 at 03:33 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 19 May 2012 at 16:13 in ♉ Taurus.

Distance to Moon 366 655 km

The Moon is 366 655 km (227 829 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 406 451 km (252 557 mi).

Moon after ascending node

1 day after ascending node on 7 May 2012 at 09:43 in ♐ Sagittarius the Moon is positioned north of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from North to South in descending node on 21 May 2012 at 09:21 in ♊ Gemini.

Moon at southern standstill

At 06:18 the Moon is meeting its standstill point to reach South declination of ∠-21.719°. Over the upcoming 13 days the lunar orbit is going to tilt northward to face maximum declination of ∠21.709° at the point of next northern standstill in ♊ Gemini on 22 May 2012 at 11:13.

Draconic month

1 day since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 12 days

In 12 days on 20 May 2012 at 23:47 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.
