Moon phase and lunation details

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 15 July 2011 at 06:40.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon in ♓ Pisces

Moon is leaving the last ∠2° of ♓ Pisces tropical zodiac sector and will enter ♈ Aries later.

Apparent angular diameter ∠1771"

Lunar disc appears visually 6.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1888".

Buck Moon before 5 days

Next Full Moon is the Sturgeon Moon of August 2011 after 24 days on 13 August 2011 at 18:58.

Upcoming main Moon phases

  • Last Quarter in Taurus ♉ on 23 July 2011 at 05:02
  • New Moon in Leo ♌ on 30 July 2011 at 18:40
  • First Quarter in Scorpio ♏ on 6 August 2011 at 11:08
  • Full Moon in Aquarius ♒ on 13 August 2011 at 18:58

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.

Lunation 142 / 1095

The Moon is 19 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 142 of Meeus index or 1095 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.41 days

The length of the lunation is 29 days, 9 hours and 46 minutes. It is 1 hour and 22 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the 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 2 hours and 58 minutes shorter than the mean synodic month length. It is 3 hours and 11 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠283.1°

At the beginning of the lunation cycle the true anomaly is ∠283.1°. At the beginning of next synodic month the true anomaly is going to be ∠312.1°.

Moon before perigee

12 days after point of perigee on 7 July 2011 at 14:04 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 day, until the Moon reaches the point of next apogee on 21 July 2011 at 22:46 in ♈ Aries.

Previous perigeeNext apogee

Distance to Moon 404 622 km

The Moon is 404 622 km (251 420 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 358 km (251 256 mi).

Moon before descending node

7 days after ascending node on 13 July 2011 at 02:27 in ♐ Sagittarius. The Moon is located north of the ecliptic over the following 7 days, until the lunar orbit crosses from North to South in descending node on 27 July 2011 at 12:03 in ♊ Gemini.

Previous nodeNext node

Draconic month

7 days since the beginning of current draconic month in ♐ Sagittarius, the Moon is navigating from the beginning to the first part of the cycle.

Moon before northern standstill

7 days since the previous standstill on 12 July 2011 at 16:51 in ♐ Sagittarius when the Moon has reached South declination of ∠-23.383°, the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠23.333° at the point of next northern standstill on 27 July 2011 at 03:02 in ♊ Gemini.

Syzygy in 10 days

In 10 days on 30 July 2011 at 18:40 in ♌ Leo 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.
