Waning Gibbous in Libra

Waning Gibbous on . The illuminated surface of the moon is 78% and getting smaller. The lunar cycle is 19 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 ∠21° of ♎ Libra tropical zodiac sector.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 8 February 2058 at 15:54.

Snow Moon before 4 days

Next Full Moon is the Worm Moon of March 2058 after 24 days on 10 March 2058 at 08:52.

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 ∠1873"

Lunar disc appears visually 3.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1873" and ∠1943".

Lunation 718 / 1671

The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 718 of Meeus index or 1671 from Brown series.

Synodic month length 29.45 days

The length of this lunation is 29 days, 10 hours and 42 minutes and it is 11 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2058. 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 shorter than mean

The length of the current synodic month is 2 hours and 2 minutes shorter than the mean synodic month length. It is 4 hours and 7 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠10.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠10.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠28.2°.

Moon before perigee

7 days since point of apogee on 5 February 2058 at 12:03 in ♋ Cancer the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next perigee on 21 February 2058 at 06:06 in ♒ Aquarius.

Distance to Moon 382 698 km

The Moon is 382 698 km (237 798 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 361 268 km (224 482 mi).

Moon before descending node

9 days after ascending node on 3 February 2058 at 20:37 in ♊ Gemini 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 18 February 2058 at 00:21 in ♐ Sagittarius.

Moon before southern standstill

8 days since the last northern standstill on 5 February 2058 at 09:27 in ♋ Cancer when the Moon has reached North declination of ∠24.565° the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-24.665° at the point of next southern standstill on 19 February 2058 at 08:23 in ♑ Capricorn.

Draconic month

9 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 9 days

In 9 days on 22 February 2058 at 22:56 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.
