Waning Gibbous in Aries

Waning Gibbous on . The illuminated surface of the moon is 77% and getting smaller. The lunar cycle is 19 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 ♈ Aries

Moon is passing about ∠14° of ♈ Aries tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 4 August 2001 at 05:56.

Sturgeon Moon before 5 days

Next Full Moon is the Harvest Moon of September 2001 after 24 days on 2 September 2001 at 21:43.

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 ∠1798"

Lunar disc appears visually 5.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1798" and ∠1893".

Lunation 19 / 972

The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 19 of Meeus index or 972 from Brown series.

Synodic month length 29.3 days

The length of this lunation is 29 days, 7 hours and 11 minutes and it is 21 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2001. 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 5 hours and 33 minutes shorter than the mean synodic month length. It is 36 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠342.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠342.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠358.1°.

Moon after apogee

3 days since point of apogee on 5 August 2001 at 21:05 in ♒ Aquarius 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 19 August 2001 at 05:43 in ♌ Leo.

Distance to Moon 398 632 km

The Moon is 398 632 km (247 698 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 357 159 km (221 928 mi).

Moon before ascending node

8 days after descending node on 1 August 2001 at 06:21 in ♑ Capricorn the Moon is positioned south of the ecliptic over the following 6 days until the lunar crosses the ecliptic again from South to North in ascending node on 15 August 2001 at 17:05 in ♊ Gemini.

Moon before northern standstill

7 days since the last southern standstill on 1 August 2001 at 18:05 in ♑ Capricorn when the Moon has reached South declination of ∠-23.427° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠23.488° at the point of next northern standstill on 16 August 2001 at 03:52 in ♋ Cancer.

Draconic month

21 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 9 days

In 9 days on 19 August 2001 at 02:55 in ♌ Leo 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.
