Waning Gibbous in Taurus

Waning Gibbous on . The illuminated surface of the moon is 73% 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.

Moon phase and lunation details

Moon in ♉ Taurus

Moon is passing about ∠16° of ♉ Taurus tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 30 August 2099 at 17:56.

Sturgeon Moon before 5 days

Next Full Moon is the Harvest Moon of September 2099 after 23 days on 29 September 2099 at 10:45.

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 ∠1800"

Lunar disc appears visually 5.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1800" and ∠1904".

Lunation 1232 / 2185

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1232 of Meeus index or 2185 from Brown series.

Synodic month length 29.33 days

The length of this lunation is 29 days, 7 hours and 56 minutes and it is 46 minutes shorter 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 4 hours and 48 minutes shorter than the mean synodic month length. It is 1 hour and 21 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠339.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠339.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠355.4°.

Moon after apogee

3 days since point of apogee on 1 September 2099 at 19:45 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next perigee on 14 September 2099 at 23:26 in ♍ Virgo.

Distance to Moon 398 307 km

The Moon is 398 307 km (247 496 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 357 286 km (222 007 mi).

Moon after ascending node

4 days after ascending node on 1 September 2099 at 08:09 in ♓ Pisces the Moon is positioned north of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from North to South in descending node on 14 September 2099 at 23:44 in ♍ Virgo.

Moon before northern standstill

11 days since the last southern standstill on 25 August 2099 at 05:13 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.632° the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠28.676° at the point of next northern standstill on 8 September 2099 at 23:00 in ♊ Gemini.

Draconic month

4 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 9 days

In 9 days on 14 September 2099 at 16:50 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.
