Moon phase and lunation details

Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon is entering ♉ Taurus

Moon is passing first ∠4° of ♉ Taurus tropical zodiac sector.

Apparent angular diameter ∠1968"

Lunar disc appears visually 0.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1968" and ∠1950".

Wolf Moon after 6 days

Next Full Moon is the Wolf Moon of January 2016 after 6 days on 24 January 2016 at 01:46.

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 198 / 1151

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 198 of Meeus index or 1151 from Brown series.

Synodic month length 29.55 days

The length of the lunation is 29 days, 13 hours and 8 minutes. It is 1 hour and 52 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 24 minutes longer than the mean synodic month length. It is 6 hours and 39 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠292.2°

At the beginning of the lunation cycle the true anomaly is ∠292.2°. At the beginning of next synodic month the true anomaly is going to be ∠319.8°.

Moon after perigee

2 days after point of perigee on 15 January 2016 at 02:10 in ♓ Pisces. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 12 days, until the Moon reaches the point of next apogee on 30 January 2016 at 09:10 in ♎ Libra.

Distance to Moon 364 176 km

The Moon is 364 176 km (226 288 mi) away from Earth and getting further over the next 12 days until the point apogee when Earth-Moon distance is going to be 404 553 km (251 378 mi).

Moon after descending node

2 days after descending node on 14 January 2016 at 15:48 in ♓ Pisces. The Moon is located south of the ecliptic over the following 10 days, until the lunar orbit crosses from South to North in ascending node on 27 January 2016 at 23:58 in ♍ Virgo.

Draconic month

16 days since the beginning of current draconic month in ♍ Virgo, the Moon is navigating from the second to the final part of the cycle.

Moon before northern standstill

8 days since the previous standstill on 8 January 2016 at 17:56 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.420°, the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠18.375° at the point of next northern standstill on 21 January 2016 at 16:41 in ♊ Gemini.

Syzygy in 6 days

In 6 days on 24 January 2016 at 01:46 in ♌ Leo the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
