Waning Crescent in Sagittarius

Waning Crescent on . The illuminated surface of the moon is 31% and getting smaller. The lunar cycle is 24 days old.

Moonrise and moonset

The moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon phase and lunation details

Moon in ♐ Sagittarius

Moon is passing about ∠11° of ♐ Sagittarius tropical zodiac sector.

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 4 February 2021 at 17:37.

Snow Moon after 20 days

Next Full Moon is the Snow Moon of February 2021 after 20 days on 27 February 2021 at 08:17.

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 ∠1960"

Lunar disc appears visually 0.8% wider than solar disc. Moon and Sun apparent angular diameters are ∠1960" and ∠1945".

Lunation 260 / 1213

The Moon is 24 days old and navigating from the second to the final part of the current synodic month. This is lunation 260 of Meeus index or 1213 from Brown series.

Synodic month length 29.59 days

The length of this lunation is 29 days, 14 hours and 5 minutes and it is 1 hour and 10 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 21 minutes longer than the mean synodic month length. It is 5 hours and 42 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠53.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠53.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠87°.

Moon after perigee

2 days since point of perigee on 3 February 2021 at 19:33 in ♎ Libra the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next apogee on 18 February 2021 at 10:22 in ♉ Taurus.

Distance to Moon 365 683 km

The Moon is 365 683 km (227 225 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 404 467 km (251 324 mi).

Moon before descending node

12 days after ascending node on 24 January 2021 at 21:47 in ♊ Gemini the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 7 February 2021 at 00:29 in ♐ Sagittarius.

Moon before southern standstill

10 days since the last northern standstill on 26 January 2021 at 15:39 in ♋ Cancer when the Moon has reached North declination of ∠24.898° the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-24.953° at the point of next southern standstill on 8 February 2021 at 15:34 in ♑ Capricorn.

Draconic month

12 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 5 days

In 5 days on 11 February 2021 at 19:06 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.
