Waning Gibbous in Gemini

Waning Gibbous on . The illuminated surface of the moon is 65% and getting smaller. The lunar cycle is 20 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.

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon is entering ♊ Gemini

Moon is passing first ∠0° of ♊ Gemini tropical zodiac sector.

6 days after Full Moon

Previous main lunar phase is the Full Moon before 6 days on 3 September 2028 at 23:48.

Harvest Moon before 6 days

Next Full Moon is the Hunter Moon of October 2028 after 23 days on 3 October 2028 at 16:25.

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 ∠1834"

Lunar disc appears visually 3.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1834" and ∠1906".

Lunation 354 / 1307

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 354 of Meeus index or 1307 from Brown series.

Synodic month length 29.32 days

The length of this lunation is 29 days, 7 hours and 40 minutes and it is 53 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2028. 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 5 hours and 4 minutes shorter than the mean synodic month length. It is 1 hour and 5 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠347.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠347.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠2.9°.

Moon after apogee

5 days since point of apogee on 4 September 2028 at 20:03 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next perigee on 18 September 2028 at 14:23 in ♍ Virgo.

Distance to Moon 390 844 km

The Moon is 390 844 km (242 859 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 357 048 km (221 859 mi).

Moon before descending node

10 days after ascending node on 30 August 2028 at 20:39 in ♑ Capricorn the Moon is positioned north of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from North to South in descending node on 14 September 2028 at 09:06 in ♋ Cancer.

Moon before northern standstill

13 days since the last southern standstill on 28 August 2028 at 06:28 in ♐ Sagittarius when the Moon has reached South declination of ∠-25.819° the lunar orbit is extending northward over the next day to face maximum declination of ∠25.693° at the point of next northern standstill on 12 September 2028 at 01:18 in ♊ Gemini.

Draconic month

10 days since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 8 days

In 8 days on 18 September 2028 at 18:24 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.
