Waning Crescent in Aries

Waning Crescent on . The illuminated surface of the moon is 41% 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 ♈ Aries

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

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 23 June 2011 at 11:48.

Buck Moon after 20 days

Next Full Moon is the Buck Moon of July 2011 after 20 days on 15 July 2011 at 06:40.

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 ∠1768"

Lunar disc appears visually 6.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1888".

Lunation 141 / 1094

The Moon is 23 days old and navigating from the second to the final part of the current synodic month. This is lunation 141 of Meeus index or 1094 from Brown series.

Synodic month length 29.49 days

The length of this lunation is 29 days, 11 hours and 51 minutes and it is 2 hours and 5 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 shorter than mean

The length of the current synodic month is 53 minutes shorter than the mean synodic month length. It is 5 hours and 16 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠248.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠248.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠283.1°.

Moon at apogee

Moon is at apogee at 04:13 about 12 days since last perigee on 12 June 2011 at 01:42 in ♏ Scorpio the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 13 days until point of next perigee on 7 July 2011 at 14:04 in ♍ Virgo.

Distance to Moon 404 275 km

This apogee Moon is 404 275 km (251 205 mi) away from Earth. This is the year's closest apogee of 2011. It is 1 133 km further than the mean apogee distance, but it is still 224 km closer than the farthest apogee of 21st century.

Moon before descending node

8 days after ascending node on 15 June 2011 at 18:35 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 30 June 2011 at 04:14 in ♊ Gemini.

Moon before northern standstill

9 days since the last southern standstill on 15 June 2011 at 08:52 in ♐ Sagittarius when the Moon has reached South declination of ∠-23.399° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠23.399° at the point of next northern standstill on 29 June 2011 at 17:46 in ♊ Gemini.

Draconic month

8 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 6 days

In 6 days on 1 July 2011 at 08:54 in ♋ Cancer 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.
