Waning Gibbous in Libra

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 ♎ Libra

Moon is passing first ∠4° of ♎ Libra tropical zodiac sector.

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 16 February 2003 at 23:51.

Snow Moon before 2 days

Next Full Moon is the Worm Moon of March 2003 after 26 days on 18 March 2003 at 10:34.

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 ∠1962"

Lunar disc appears visually 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1962" and ∠1941".

Lunation 38 / 991

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 38 of Meeus index or 991 from Brown series.

Synodic month length 29.66 days

The length of this lunation is 29 days, 15 hours and 47 minutes and it is 57 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 3 hours and 3 minutes longer than the mean synodic month length. It is 4 hours shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠90.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠90.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠127.8°.

Moon at perigee

Moon is at perigee at 16:19 about 11 days since last apogee on 7 February 2003 at 21:58 in ♈ Aries the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 16 days until point of next apogee on 7 March 2003 at 16:34 in ♉ Taurus.

Distance to Moon 364 844 km

This perigee Moon is 364 844 km (226 704 mi) away from Earth. It is 2 336 km closer than the mean perigee distance, but it is still 5 512 km further than the closest perigee of 21st century.

Moon before descending node

8 days after ascending node on 10 February 2003 at 17:39 in ♉ Taurus the Moon is positioned north of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from North to South in descending node on 23 February 2003 at 15:47 in ♏ Scorpio.

Moon after northern standstill

6 days since the last northern standstill on 13 February 2003 at 10:59 in ♋ Cancer when the Moon has reached North declination of ∠25.923° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-26.015° at the point of next southern standstill on 26 February 2003 at 05:53 in ♑ Capricorn.

Draconic month

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

Syzygy in 11 days

In 11 days on 3 March 2003 at 02:35 in ♓ Pisces 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.
