Waning Gibbous in Libra

Waning Gibbous on . The illuminated surface of the moon is 86% and getting smaller. The lunar cycle is 18 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 ♎ Libra

Moon is passing about ∠7° of ♎ Libra tropical zodiac sector.

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 8 February 2001 at 07:12.

Snow Moon before 3 days

Next Full Moon is the Worm Moon of March 2001 after 26 days on 9 March 2001 at 17:23.

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 ∠1925"

Lunar disc appears visually 1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1925" and ∠1944".

Lunation 13 / 966

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 13 of Meeus index or 966 from Brown series.

Synodic month length 29.8 days

The length of this lunation is 29 days, 19 hours and 14 minutes and it is 2 hours and 14 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2001. 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 longer than mean

The length of the current synodic month is 7 hours and 1 minute longer than the mean synodic month length. It is 33 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠177.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠177.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠202.8°.

Moon after perigee

3 days since point of perigee on 7 February 2001 at 22:19 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 9 days until the Moon reaches the point of next apogee on 20 February 2001 at 21:38 in ♑ Capricorn.

Distance to Moon 372 284 km

The Moon is 372 284 km (231 327 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 406 332 km (252 483 mi).

Moon after ascending node

5 days after ascending node on 6 February 2001 at 00:48 in ♋ Cancer 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 19 February 2001 at 02:52 in ♑ Capricorn.

Moon after northern standstill

5 days since the last northern standstill on 5 February 2001 at 19:54 in ♋ Cancer when the Moon has reached North declination of ∠22.604° the lunar orbit is extending southward over the next 7 days to face maximum declination of ∠-22.648° at the point of next southern standstill on 18 February 2001 at 21:27 in ♑ Capricorn.

Draconic month

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

Syzygy in 11 days

In 11 days on 23 February 2001 at 08:21 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.
