Waning Crescent in Gemini

Waning Crescent on . The illuminated surface of the moon is 41% and getting smaller. The lunar cycle is 23 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 ♊ Gemini

Moon is leaving the last ∠1° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 10 September 2039 at 13:45.

Hunter Moon after 20 days

Next Full Moon is the Hunter Moon of October 2039 after 20 days on 2 October 2039 at 07:23.

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 ∠1769"

Lunar disc appears visually 7.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1906".

Lunation 490 / 1443

The Moon is 23 days old and navigating from the second to the final part of the current synodic month. This is lunation 490 of Meeus index or 1443 from Brown series.

Synodic month length 29.48 days

The length of this lunation is 29 days, 11 hours and 32 minutes and it is 46 minutes longer than the upcoming lunation's length. 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 shorter than mean

The length of the current synodic month is 1 hour and 12 minutes shorter than the mean synodic month length. It is 4 hours and 57 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠260.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠260.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠294.5°.

Moon after apogee

1 day since point of apogee on 10 September 2039 at 14:24 in ♊ Gemini the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next perigee on 23 September 2039 at 02:18 in ♐ Sagittarius.

Distance to Moon 405 098 km

The Moon is 405 098 km (251 716 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 368 956 km (229 259 mi).

Moon after ascending node

1 day after ascending node on 10 September 2039 at 13:18 in ♊ Gemini the Moon is positioned north of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from North to South in descending node on 24 September 2039 at 01:47 in ♐ Sagittarius.

Moon before northern standstill

12 days since the last southern standstill on 29 August 2039 at 14:11 in ♑ Capricorn when the Moon has reached South declination of ∠-24.880° the lunar orbit is extending northward over the next day to face maximum declination of ∠24.993° at the point of next northern standstill on 12 September 2039 at 12:07 in ♋ Cancer.

Draconic month

1 day 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 6 days

In 6 days on 18 September 2039 at 08:23 in ♍ Virgo 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.
