Waxing Gibbous in Taurus

Waxing Gibbous on . Illuminated surface of the Moon is 82% and growing larger. Lunar cycle is 10 days young.

Moonrise and moonset

Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♉ Taurus

Moon is passing about ∠17° of ♉ Taurus tropical zodiac sector.

3 days after First Quarter

Previous main lunar phase is the First Quarter before 3 days on 26 December 2017 at 09:20.

Wolf Moon after 3 days

Next Full Moon is the Wolf Moon of January 2018 after 3 days on 2 January 2018 at 02:24.

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.

Apparent angular diameter ∠1940"

Lunar disc appears visually 0.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1940" and ∠1951".

Lunation 222 / 1175

The Moon is 10 days young and navigating from the first to the middle part of the current synodic month. This is lunation 222 of Meeus index or 1175 from Brown series.

Synodic month length 29.82 days

The length of this lunation is 29 days, 19 hours and 47 minutes and it is 59 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2017. The lengths of the following synodic months are going to decrease with the lunar orbit 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 7 hours and 3 minutes longer than the mean synodic month length and it is the longest synodic month length of 21st century.

Lunar orbit details for

True anomaly ∠173.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠173.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠198.1°.

Moon before perigee

10 days since point of apogee on 19 December 2017 at 01:27 in ♑ Capricorn 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 1 January 2018 at 21:54 in ♋ Cancer.

Distance to Moon 369 428 km

The Moon is 369 428 km (229 552 mi) away from Earth and getting closer over the next 3 days until the point perigee when Earth-Moon distance is going to be 356 566 km (221 560 mi).

Moon before ascending node

7 days after descending node on 22 December 2017 at 10:04 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from South to North in ascending node on 4 January 2018 at 07:48 in ♌ Leo.

Moon before northern standstill

10 days since the last southern standstill on 19 December 2017 at 09:31 in ♑ Capricorn when the Moon has reached South declination of ∠-20.062° the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠20.055° at the point of next northern standstill on 2 January 2018 at 00:01 in ♋ Cancer.

Draconic month

21 days since the beginning of this draconic month in ♌ Leo the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 3 days

In 3 days on 2 January 2018 at 02:24 in ♋ Cancer 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.
