Waning Gibbous in Sagittarius

Waning Gibbous on . Illuminated surface of the Moon is 95% 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 ∠17° of ♐ Sagittarius tropical zodiac sector.

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 9 May 2009 at 04:01.

Flower Moon before 2 days

Next Full Moon is the Strawberry Moon of June 2009 after 27 days on 7 June 2009 at 18:12.

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 ∠1779"

Lunar disc appears visually 6.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1779" and ∠1899".

Lunation 115 / 1068

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 115 of Meeus index or 1068 from Brown series.

Synodic month length 29.37 days

The length of this lunation is 29 days, 8 hours and 48 minutes and it is 1 hour and 24 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 3 hours and 56 minutes shorter than the mean synodic month length. It is 2 hours and 13 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠311.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠311.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠332.7°.

Moon before apogee

13 days since point of perigee on 28 April 2009 at 06:26 in ♊ Gemini the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next apogee on 14 May 2009 at 02:57 in ♑ Capricorn.

Distance to Moon 402 882 km

The Moon is 402 882 km (250 339 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 404 916 km (251 603 mi).

Moon before ascending node

10 days after descending node on 1 May 2009 at 07:50 in ♌ Leo the Moon is positioned south of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from South to North in ascending node on 15 May 2009 at 07:13 in ♒ Aquarius.

Moon at southern standstill

At 20:03 the Moon is meeting its standstill point to reach South declination of ∠-26.486°. Over the upcoming 14 days the lunar orbit is going to tilt northward to face maximum declination of ∠26.451° at the point of next northern standstill in ♊ Gemini on 25 May 2009 at 16:56.

Draconic month

23 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 13 days

In 13 days on 24 May 2009 at 12:11 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.
