Moon phase and lunation details

6 days after First Quarter

Previous main lunar phase is the First Quarter before 6 days on 21 December 2020 at 23:41.

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.

Moon in ♊ Gemini

Moon is passing about ∠18° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1793"

Lunar disc appears visually 8.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1793" and ∠1951".

Cold Moon after 1 day

Next Full Moon is the Cold Moon of December 2020 after 1 day on 30 December 2020 at 03:28.

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 259 / 1212

The Moon is 13 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 259 of Meeus index or 1212 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.53 days

The length of the lunation is 29 days, 12 hours and 44 minutes. It is 1 hour and 21 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 same as the mean

The length of the current synodic month is equal to the mean synodic month length. It is %hours_to_shortest% and %minutes_to_shortest% longer than the 21st century's shortest and %hours_to_longest% and %minutes_to_longest% shorter than the 21st century's longest synodic months.

Lunar orbit position on

True anomaly ∠30.1°

At the beginning of the lunation cycle the true anomaly is ∠30.1°. At the beginning of next synodic month the true anomaly is going to be ∠53.8°.

Moon after apogee

3 days after point of apogee on 24 December 2020 at 16:32 in ♈ Aries. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 12 days, until the Moon reaches the point of next perigee on 9 January 2021 at 15:39 in ♏ Scorpio.

Previous apogeeNext perigee

Distance to Moon 399 794 km

The Moon is 399 794 km (248 420 mi) away from Earth and getting closer over the next 12 days until the point perigee when Earth-Moon distance is going to be 367 390 km (228 286 mi).

Moon in ascending node

Moon is in ascending node in ♊ Gemini at 15:03 crossing the ecliptic from South to North to meet descending node 13 days later on 10 January 2021 at 20:15 in ♐ Sagittarius.

Previous nodeNext node

New draconic month

At 15:03 the Moon completes the previous draconic month and enters the new one.

Moon before northern standstill

12 days since the previous standstill on 15 December 2020 at 22:23 in ♑ Capricorn when the Moon has reached South declination of ∠-24.879°, the lunar orbit is extending northward over the next day to face maximum declination of ∠24.868° at the point of next northern standstill on 30 December 2020 at 07:53 in ♋ Cancer.

Previous standstillNext standstill

Syzygy in 1 day

In 1 day on 30 December 2020 at 03:28 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.
