Moon phase and lunation details

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 29 July 2013 at 17:43.

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.

Moon in ♉ Taurus

Moon is leaving the last ∠2° of ♉ Taurus tropical zodiac sector and will enter ♊ Gemini later.

Apparent angular diameter ∠1788"

Lunar disc appears visually 5.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1788" and ∠1890".

Sturgeon Moon after 20 days

Next Full Moon is the Sturgeon Moon of August 2013 after 20 days on 21 August 2013 at 01:45.

Upcoming main Moon phases

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.

Lunation 167 / 1120

The Moon is 23 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 167 of Meeus index or 1120 from Brown series.

Synodic month length 29.61 days

The length of the lunation is 29 days, 14 hours and 36 minutes. It is 51 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 longer than mean

The length of the current synodic month is 1 hour and 52 minutes longer than the mean synodic month length. It is 5 hours and 11 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠191.6°

At the beginning of the lunation cycle the true anomaly is ∠191.6°. At the beginning of next synodic month the true anomaly is going to be ∠216.9°.

Moon before perigee

9 days after point of perigee on 21 July 2013 at 20:27 in ♑ Capricorn. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 2 days, until the Moon reaches the point of next apogee on 3 August 2013 at 08:53 in ♋ Cancer.

Previous perigeeNext apogee

Distance to Moon 400 799 km

The Moon is 400 799 km (249 045 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 405 834 km (252 174 mi).

Moon after descending node

1 day after descending node on 30 July 2013 at 05:50 in ♉ Taurus. The Moon is located south of the ecliptic over the following 13 days, until the lunar orbit crosses from South to North in ascending node on 13 August 2013 at 16:20 in ♏ Scorpio.

Draconic month

13 days since the beginning of current draconic month in ♏ Scorpio, the Moon is navigating from the second to the final part of the cycle.

Moon before northern standstill

11 days since the previous standstill on 20 July 2013 at 03:12 in ♐ Sagittarius when the Moon has reached South declination of ∠-20.097°, the lunar orbit is extending northward over the next day to face maximum declination of ∠20.025° at the point of next northern standstill on 2 August 2013 at 09:24 in ♊ Gemini.

Syzygy in 6 days

In 6 days on 6 August 2013 at 21:51 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.
