Waning Gibbous in Taurus

Waning Gibbous on . Illuminated surface of the Moon is 86% and getting smaller. Lunar cycle is 18 days old.

Moonrise and moonset

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.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♉ Taurus

Moon is passing about ∠9° of ♉ Taurus tropical zodiac sector.

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 13 September 2038 at 12:24.

Harvest Moon before 3 days

Next Full Moon is the Hunter Moon of October 2038 after 25 days on 13 October 2038 at 04:22.

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 ∠1909".

Lunation 478 / 1431

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 478 of Meeus index or 1431 from Brown series.

Synodic month length 29.36 days

The length of this lunation is 29 days, 8 hours and 45 minutes and it is 10 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2038. 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 3 hours and 59 minutes shorter than the mean synodic month length. It is 2 hours and 10 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠319.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠319.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠339.4°.

Moon at apogee

Moon is at apogee at 19:15 about 15 days since last perigee on 1 September 2038 at 22:39 in ♎ Libra 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 2038 at 00:20 in ♏ Scorpio.

Distance to Moon 405 516 km

This apogee Moon is 405 516 km (251 976 mi) away from Earth. It is 108 km further than the mean apogee distance, but it is still 1 193 km closer than the farthest apogee of 21st century.

Moon before ascending node

9 days after descending node on 7 September 2038 at 20:51 in ♑ Capricorn the Moon is positioned south of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from South to North in ascending node on 22 September 2038 at 07:26 in ♋ Cancer.

Moon before northern standstill

9 days since the last southern standstill on 8 September 2038 at 03:20 in ♑ Capricorn when the Moon has reached South declination of ∠-23.232° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠23.372° at the point of next northern standstill on 22 September 2038 at 17:24 in ♋ Cancer.

Draconic month

22 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 11 days

In 11 days on 28 September 2038 at 18:57 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.
