Moon phase and lunation details

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 3 February 2013 at 13:56.

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 ♏ Scorpio

Moon is leaving the last ∠2° of ♏ Scorpio tropical zodiac sector and will enter ♐ Sagittarius later.

Apparent angular diameter ∠1968"

Lunar disc appears visually 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1968" and ∠1946".

Snow Moon after 21 days

Next Full Moon is the Snow Moon of February 2013 after 21 days on 25 February 2013 at 20:26.

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 161 / 1114

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 161 of Meeus index or 1114 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.48 days

The length of the lunation is 29 days, 11 hours and 36 minutes. It is 55 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length shorter than mean

The length of the current synodic month is 1 hour and 8 minutes shorter than the mean synodic month length. It is 5 hours and 1 minute longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠23.3°

At the beginning of the lunation cycle the true anomaly is ∠23.3°. At the beginning of next synodic month the true anomaly is going to be ∠44.2°.

Moon before apogee

13 days after point of apogee on 22 January 2013 at 10:52 in ♊ Gemini. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 3 days, until the Moon reaches the point of next perigee on 7 February 2013 at 12:09 in ♑ Capricorn.

Previous apogeeNext perigee

Distance to Moon 364 242 km

The Moon is 364 242 km (226 329 mi) away from Earth and getting closer over the next 3 days until the point perigee when Earth-Moon distance is going to be 365 314 km (226 996 mi).

Moon in ascending node

Moon is in ascending node in ♏ Scorpio at 02:14 crossing the ecliptic from South to North to meet descending node 12 days later on 17 February 2013 at 02:57 in ♉ Taurus.

Previous nodeNext node

New draconic month

At 02:14 the Moon completes the previous draconic month and enters the new one.

Moon before southern standstill

12 days since the previous standstill on 23 January 2013 at 05:12 in ♊ Gemini when the Moon has reached North declination of ∠20.816°, the lunar orbit is extending southward over the next day to face maximum declination of ∠-20.704° at the point of next southern standstill on 6 February 2013 at 00:27 in ♐ Sagittarius.

Previous standstillNext standstill

Syzygy in 5 days

In 5 days on 10 February 2013 at 07:20 in ♒ Aquarius 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.
