Waning Crescent in Aries

Waning Crescent on . Illuminated surface of the Moon is 12% and getting smaller. Lunar cycle is 26 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 ∠6° of ♈ Aries tropical zodiac sector.

4 days after Last Quarter

Previous main lunar phase is the Last Quarter before 4 days on 2 May 2013 at 11:14.

Flower Moon after 18 days

Next Full Moon is the Flower Moon of May 2013 after 18 days on 25 May 2013 at 04:25.

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 ∠1853"

Lunar disc appears visually 2.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1853" and ∠1902".

Lunation 164 / 1117

The Moon is 26 days old and navigating from the second to the final part of the current synodic month. This is lunation 164 of Meeus index or 1117 from Brown series.

Synodic month length 29.62 days

The length of this lunation is 29 days, 14 hours and 53 minutes and it is 35 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length longer than mean

The length of the current synodic month is 2 hours and 9 minutes longer than the mean synodic month length. It is 4 hours and 54 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠110.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠110.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠143.3°.

Moon before apogee

8 days since point of perigee on 27 April 2013 at 19:48 in ♏ Scorpio the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next apogee on 13 May 2013 at 13:31 in ♊ Gemini.

Distance to Moon 386 809 km

The Moon is 386 809 km (240 352 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 405 827 km (252 169 mi).

Moon before descending node

9 days after ascending node on 26 April 2013 at 14:07 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from North to South in descending node on 9 May 2013 at 19:12 in ♉ Taurus.

Moon before northern standstill

7 days since the last southern standstill on 28 April 2013 at 19:05 in ♐ Sagittarius when the Moon has reached South declination of ∠-20.170° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠20.170° at the point of next northern standstill on 12 May 2013 at 12:30 in ♊ Gemini.

Draconic month

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

Syzygy in 3 days

In 3 days on 10 May 2013 at 00:29 in ♉ Taurus 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.
