Moon phase and lunation details

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 27 January 2013 at 04:38.

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 ♌ Leo

Moon is passing about ∠24° of ♌ Leo tropical zodiac sector.

Apparent angular diameter ∠1831"

Lunar disc appears visually 6.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1831" and ∠1948".

Wolf Moon before 1 day

Next Full Moon is the Snow Moon of February 2013 after 28 days on 25 February 2013 at 20:26.

Upcoming main Moon phases

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 161 / 1114

The Moon is 16 days old. Earth's natural satellite is moving from the middle to the last 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 after apogee

6 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 10 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 391 365 km

The Moon is 391 365 km (243 183 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 365 314 km (226 996 mi).

Moon before ascending node

7 days after descending node on 21 January 2013 at 01:19 in ♉ Taurus. The Moon is located south of the ecliptic over the following 6 days, until the lunar orbit crosses from South to North in ascending node on 4 February 2013 at 02:14 in ♏ Scorpio.

Draconic month

20 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 after northern standstill

5 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 8 days to face maximum declination of ∠-20.704° at the point of next southern standstill on 6 February 2013 at 00:27 in ♐ Sagittarius.

Syzygy in 12 days

In 12 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.
