Waning Crescent in Aquarius

Waning Crescent on . The illuminated surface of the moon is 40% and getting smaller. The lunar cycle is 23 days old.

Moonrise and moonset

The moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon phase and lunation details

Moon in ♒ Aquarius

Moon is passing about ∠6° of ♒ Aquarius tropical zodiac sector.

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 12 April 2099 at 10:47.

Flower Moon after 21 days

Next Full Moon is the Flower Moon of May 2099 after 21 days on 4 May 2099 at 17:58.

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Apparent angular diameter ∠1789"

Lunar disc appears visually 6.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1789" and ∠1913".

Lunation 1227 / 2180

The Moon is 23 days old and navigating from the second to the final part of the current synodic month. This is lunation 1227 of Meeus index or 2180 from Brown series.

Synodic month length 29.7 days

The length of this lunation is 29 days, 16 hours and 43 minutes and it is 2 hours and 56 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 longer than mean

The length of the current synodic month is 3 hours and 59 minutes longer than the mean synodic month length. It is 3 hours and 4 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠199.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠199.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠227.5°.

Moon before apogee

9 days since point of perigee on 4 April 2099 at 03:23 in ♍ Virgo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next apogee on 16 April 2099 at 08:34 in ♓ Pisces.

Distance to Moon 400 674 km

The Moon is 400 674 km (248 967 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 405 586 km (252 019 mi).

Moon before ascending node

8 days after descending node on 4 April 2099 at 16:08 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from South to North in ascending node on 18 April 2099 at 13:19 in ♓ Pisces.

Moon after southern standstill

2 days since the last southern standstill on 10 April 2099 at 17:12 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.656° the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠28.599° at the point of next northern standstill on 25 April 2099 at 08:16 in ♋ Cancer.

Draconic month

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

Syzygy in 7 days

In 7 days on 20 April 2099 at 15:30 in ♈ Aries 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.
