Waning Crescent in Aries

Waning Crescent on . The illuminated surface of the moon is 1% and getting smaller. The lunar cycle is 28 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 is entering ♈ Aries

Moon is passing first ∠0° of ♈ Aries tropical zodiac sector.

6 days after Last Quarter

Previous main lunar phase is the Last Quarter before 6 days on 26 March 2011 at 12:07.

Pink Moon after 15 days

Next Full Moon is the Pink Moon of April 2011 after 15 days on 18 April 2011 at 02:44.

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 ∠1768"

Lunar disc appears visually 8.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1919".

Lunation 138 / 1091

The Moon is 28 days old and navigating from the second to the final part of the current synodic month. This is lunation 138 of Meeus index or 1091 from Brown series.

Synodic month length 29.74 days

The length of this lunation is 29 days, 17 hours and 46 minutes and it is 1 hour and 28 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 5 hours and 2 minutes longer than the mean synodic month length. It is 2 hours and 1 minute shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠167°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠167° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠190.9°.

Moon at apogee

Moon is at apogee at 09:00 about 13 days since last perigee on 19 March 2011 at 19:09 in ♍ Virgo the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 14 days until point of next perigee on 17 April 2011 at 05:59 in ♎ Libra.

Distance to Moon 406 656 km

This apogee Moon is 406 656 km (252 684 mi) away from Earth. This is the year's farthest apogee of 2011. It is 1 248 km further than the mean apogee distance, but it is still 53 km closer than the farthest apogee of 21st century.

Moon before descending node

7 days after ascending node on 25 March 2011 at 21:09 in ♐ Sagittarius the Moon is positioned north of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from North to South in descending node on 9 April 2011 at 12:48 in ♊ Gemini.

Moon before northern standstill

8 days since the last southern standstill on 25 March 2011 at 05:02 in ♐ Sagittarius when the Moon has reached South declination of ∠-23.716° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠23.569° at the point of next northern standstill on 8 April 2011 at 22:55 in ♊ Gemini.

Draconic month

7 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 1 day

In 1 day on 3 April 2011 at 14:32 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.
