Waning Gibbous in Sagittarius

Waning Gibbous on . The illuminated surface of the moon is 97% and getting smaller. The lunar cycle is 16 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 ∠4° of ♐ Sagittarius tropical zodiac sector and will enter ♑ Capricorn later.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 27 May 2010 at 23:07.

Flower Moon before 1 day

Next Full Moon is the Strawberry Moon of June 2010 after 27 days on 26 June 2010 at 11:30.

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 ∠1820"

Lunar disc appears visually 3.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1820" and ∠1893".

Lunation 128 / 1081

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 128 of Meeus index or 1081 from Brown series.

Synodic month length 29.42 days

The length of this lunation is 29 days, 10 hours and 10 minutes and it is 1 hour and 44 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 2 hours and 34 minutes shorter than the mean synodic month length. It is 3 hours and 35 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠282.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠282.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠311.3°.

Moon before apogee

9 days since point of perigee on 20 May 2010 at 08:38 in ♌ Leo 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 3 June 2010 at 16:50 in ♒ Aquarius.

Distance to Moon 393 780 km

The Moon is 393 780 km (244 684 mi) away from Earth and getting further over the next 5 days until the point apogee when Earth-Moon distance is going to be 404 266 km (251 199 mi).

Moon before ascending node

11 days after descending node on 17 May 2010 at 15:39 in ♋ Cancer the Moon is positioned south of the ecliptic over the following day until the lunar crosses the ecliptic again from South to North in ascending node on 30 May 2010 at 18:07 in ♑ Capricorn.

Moon after southern standstill

1 day since the last southern standstill on 28 May 2010 at 22:09 in ♐ Sagittarius when the Moon has reached South declination of ∠-25.029° the lunar orbit is extending northward over the next 13 days to face maximum declination of ∠25.030° at the point of next northern standstill on 12 June 2010 at 07:06 in ♊ Gemini.

Draconic month

25 days since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 13 days

In 13 days on 12 June 2010 at 11:15 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.
