Waning Gibbous in Libra

Waning Gibbous on . The illuminated surface of the moon is 95% and getting smaller. The lunar cycle is 17 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 is entering ♎ Libra

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

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 24 February 2100 at 14:51.

Snow Moon before 1 day

Next Full Moon is the Worm Moon of March 2100 after 27 days on 26 March 2100 at 01:05.

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 ∠1969"

Lunar disc appears visually 1.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1969" and ∠1938".

Lunation 1238 / 2191

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1238 of Meeus index or 2191 from Brown series.

Synodic month length 29.73 days

The length of this lunation is 29 days, 17 hours and 34 minutes and it is 14 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 4 hours and 50 minutes longer than the mean synodic month length. It is 2 hours and 13 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠119.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠119.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠151.4°.

Moon at perigee

Moon is at perigee at 05:17 about 11 days since last apogee on 14 February 2100 at 06:46 in ♈ Aries the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 15 days until point of next apogee on 13 March 2100 at 21:09 in ♈ Aries.

Distance to Moon 360 805 km

This perigee Moon is 360 805 km (224 194 mi) away from Earth. It is 1 703 km closer than the mean perigee distance, but it is still 9 551 km further than the closest perigee of 21st century.

Moon after descending node

1 day after descending node on 25 February 2100 at 09:12 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from South to North in ascending node on 10 March 2100 at 16:27 in ♓ Pisces.

Moon before southern standstill

6 days since the last northern standstill on 19 February 2100 at 17:35 in ♊ Gemini when the Moon has reached North declination of ∠28.552° the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-28.575° at the point of next southern standstill on 4 March 2100 at 09:17 in ♐ Sagittarius.

Draconic month

15 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 12 days

In 12 days on 10 March 2100 at 22:28 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.
