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 is entering ♐ Sagittarius

Moon is passing first ∠0° of ♐ Sagittarius tropical zodiac sector.

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 16 May 2022 at 04:14.

Flower Moon before 2 days

Next Full Moon is the Strawberry Moon of June 2022 after 26 days on 14 June 2022 at 11:52.

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 ∠1973"

Lunar disc appears visually 3.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1897".

Lunation 276 / 1229

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 276 of Meeus index or 1229 from Brown series.

Synodic month length 29.63 days

The length of this lunation is 29 days, 15 hours and 2 minutes and it is 20 minutes shorter than the upcoming lunation's length. 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 2 hours and 18 minutes longer than the mean synodic month length. It is 4 hours and 45 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠126°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠126° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠155.2°.

Moon after perigee

1 day since point of perigee on 17 May 2022 at 15:23 in ♐ Sagittarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 14 days until the Moon reaches the point of next apogee on 2 June 2022 at 01:14 in ♋ Cancer.

Distance to Moon 363 356 km

The Moon is 363 356 km (225 779 mi) away from Earth and getting further over the next 14 days until the point apogee when Earth-Moon distance is going to be 406 191 km (252 395 mi).

Moon after descending node

2 days after descending node on 15 May 2022 at 23:44 in ♏ Scorpio the Moon is positioned south of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from South to North in ascending node on 29 May 2022 at 02:33 in ♉ Taurus.

Moon before southern standstill

12 days since the last northern standstill on 5 May 2022 at 15:55 in ♋ Cancer when the Moon has reached North declination of ∠26.967° the lunar orbit is extending southward over the next day to face maximum declination of ∠-26.964° at the point of next southern standstill on 19 May 2022 at 01:21 in ♑ Capricorn.

Draconic month

16 days since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 11 days

In 11 days on 30 May 2022 at 11:30 in ♊ Gemini 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.
