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 in ♉ Taurus

Moon is passing about ∠9° of ♉ Taurus tropical zodiac sector.

Apparent angular diameter ∠1855"

Lunar disc appears visually 5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1855" and ∠1951".

Wolf Moon after 5 days

Next Full Moon is the Wolf Moon of January 2019 after 5 days on 21 January 2019 at 05:16.

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 235 / 1188

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 235 of Meeus index or 1188 from Brown series.

Synodic month length 29.82 days

The length of the lunation is 29 days, 19 hours and 35 minutes. This is the year's longest synodic month of 2019. It is 35 minutes longer 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 longer than mean

The length of the current synodic month is 6 hours and 51 minutes longer than the mean synodic month length. It is 12 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠149.4°

At the beginning of the lunation cycle the true anomaly is ∠149.4°. At the beginning of next synodic month the true anomaly is going to be ∠175.6°.

Moon after apogee

6 days after point of apogee on 9 January 2019 at 04:29 in ♒ Aquarius. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 6 days, until the Moon reaches the point of next perigee on 21 January 2019 at 19:58 in ♌ Leo.

Distance to Moon 386 335 km

The Moon is 386 335 km (240 057 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 357 345 km (222 044 mi).

Moon before ascending node

8 days after descending node on 7 January 2019 at 00:08 in ♒ Aquarius. The Moon is located south of the ecliptic over the following 5 days, until the lunar orbit crosses from South to North in ascending node on 20 January 2019 at 22:48 in ♋ Cancer.

Draconic month

22 days since the beginning of current draconic month in ♋ Cancer, the Moon is navigating from the second to the final part of the cycle.

Moon before northern standstill

9 days since the previous standstill on 5 January 2019 at 18:45 in ♑ Capricorn when the Moon has reached South declination of ∠-21.553°, the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠21.544° at the point of next northern standstill on 19 January 2019 at 23:20 in ♋ Cancer.

Syzygy in 5 days

In 5 days on 21 January 2019 at 05:16 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.
