Waning Crescent in Aries

Waning Crescent on . Illuminated surface of the Moon is 18% and getting smaller. Lunar cycle is 25 days old.

Moonrise and moonset

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

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♈ Aries

Moon is passing about ∠18° of ♈ Aries tropical zodiac sector.

3 days after Last Quarter

Previous main lunar phase is the Last Quarter before 3 days on 24 May 2011 at 18:52.

Strawberry Moon after 18 days

Next Full Moon is the Strawberry Moon of June 2011 after 18 days on 15 June 2011 at 20:13.

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 ∠1769"

Lunar disc appears visually 6.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1893".

Lunation 140 / 1093

The Moon is 25 days old and navigating from the second to the final part of the current synodic month. This is lunation 140 of Meeus index or 1093 from Brown series.

Synodic month length 29.59 days

The length of this lunation is 29 days, 14 hours and 12 minutes and it is 2 hours and 21 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 1 hour and 28 minutes longer than the mean synodic month length. It is 5 hours and 35 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠216.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠216.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠248.4°.

Moon after apogee

1 day since point of apogee on 27 May 2011 at 09:58 in ♈ Aries the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 14 days until the Moon reaches the point of next perigee on 12 June 2011 at 01:42 in ♏ Scorpio.

Distance to Moon 405 127 km

The Moon is 405 127 km (251 734 mi) away from Earth and getting closer over the next 14 days until the point perigee when Earth-Moon distance is going to be 367 188 km (228 160 mi).

Moon before descending node

9 days after ascending node on 19 May 2011 at 09:03 in ♐ Sagittarius the Moon is positioned north of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from North to South in descending node on 2 June 2011 at 20:21 in ♊ Gemini.

Moon before northern standstill

9 days since the last southern standstill on 18 May 2011 at 23:26 in ♐ Sagittarius when the Moon has reached South declination of ∠-23.403° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠23.393° at the point of next northern standstill on 2 June 2011 at 09:54 in ♊ Gemini.

Draconic month

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

Syzygy in 4 days

In 4 days on 1 June 2011 at 21:03 in ♊ Gemini 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.
