Waning Gibbous in Leo

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 ♌ Leo

Moon is leaving the last ∠4° of ♌ Leo tropical zodiac sector and will enter ♍ Virgo later.

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 18 January 2003 at 10:48.

Wolf Moon before 2 days

Next Full Moon is the Snow Moon of February 2003 after 27 days on 16 February 2003 at 23:51.

Neap tide

There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

Apparent angular diameter ∠1919"

Lunar disc appears visually 1.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1919" and ∠1950".

Lunation 37 / 990

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 37 of Meeus index or 990 from Brown series.

Synodic month length 29.6 days

The length of this lunation is 29 days, 14 hours and 26 minutes and it is 1 hour and 21 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 1 hour and 41 minutes longer than the mean synodic month length. It is 5 hours and 21 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠56.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠56.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠90.6°.

Moon before perigee

9 days since point of apogee on 11 January 2003 at 00:43 in ♉ Taurus the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next perigee on 23 January 2003 at 22:43 in ♎ Libra.

Distance to Moon 373 568 km

The Moon is 373 568 km (232 124 mi) away from Earth and getting closer over the next 3 days until the point perigee when Earth-Moon distance is going to be 369 912 km (229 853 mi).

Moon after ascending node

5 days after ascending node on 14 January 2003 at 13:38 in ♊ Gemini the Moon is positioned north of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from North to South in descending node on 27 January 2003 at 15:23 in ♏ Scorpio.

Moon after northern standstill

3 days since the last northern standstill on 17 January 2003 at 02:11 in ♋ Cancer when the Moon has reached North declination of ∠25.794° the lunar orbit is extending southward over the next 9 days to face maximum declination of ∠-25.834° at the point of next southern standstill on 30 January 2003 at 00:31 in ♑ Capricorn.

Draconic month

5 days since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 11 days

In 11 days on 1 February 2003 at 10:48 in ♒ Aquarius 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.
