Waning Gibbous in Gemini

Waning Gibbous on . The illuminated surface of the moon is 62% and getting smaller. The lunar cycle is 21 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 ♊ Gemini

Moon is passing about ∠11° of ♊ Gemini tropical zodiac sector.

6 days after Full Moon

Previous main lunar phase is the Full Moon before 6 days on 11 September 2030 at 21:18.

Harvest Moon before 6 days

Next Full Moon is the Hunter Moon of October 2030 after 22 days on 11 October 2030 at 10:47.

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 ∠1768"

Lunar disc appears visually 7.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1910".

Lunation 379 / 1332

The Moon is 21 days old and navigating from the middle to the last part of the current synodic month. This is lunation 379 of Meeus index or 1332 from Brown series.

Synodic month length 29.45 days

The length of this lunation is 29 days, 10 hours and 47 minutes and it is 25 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 57 minutes shorter than the mean synodic month length. It is 4 hours and 12 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠279.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠279.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠310.2°.

Moon at apogee

Moon is at apogee at 18:09 about 14 days since last perigee on 4 September 2030 at 17:06 in ♐ Sagittarius the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 12 days until point of next perigee on 30 September 2030 at 15:39 in ♏ Scorpio.

Distance to Moon 404 258 km

This apogee Moon is 404 258 km (251 194 mi) away from Earth. It is 1 150 km further than the mean apogee distance, but it is still 2 451 km closer than the farthest apogee of 21st century.

Moon in descending node

Moon is in descending node in ♊ Gemini at 10:12 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 13 days until Moon's next ascending node later on 1 October 2030 at 22:00 in ♐ Sagittarius.

Moon before northern standstill

13 days since the last southern standstill on 5 September 2030 at 08:00 in ♐ Sagittarius when the Moon has reached South declination of ∠-22.341° the lunar orbit is extending northward over the next day to face maximum declination of ∠22.208° at the point of next northern standstill on 19 September 2030 at 02:24 in ♊ Gemini.

Draconic month

13 days since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 8 days

In 8 days on 27 September 2030 at 09:55 in ♎ Libra 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.
