Moon phase and lunation details

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 2 December 2009 at 07:30.

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 ♊ Gemini

Moon is leaving the last ∠2° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.

Apparent angular diameter ∠1949"

Lunar disc appears visually 0.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1949" and ∠1947".

Cold Moon before 1 day

Next Full Moon is the Cold Moon of December 2009 after 28 days on 31 December 2009 at 19:13.

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 122 / 1075

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 122 of Meeus index or 1075 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.7 days

The length of the lunation is 29 days, 16 hours and 48 minutes. It is 2 hours 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 longer than mean

The length of the current synodic month is 4 hours and 4 minutes longer than the mean synodic month length. It is 2 hours and 59 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠99.9°

At the beginning of the lunation cycle the true anomaly is ∠99.9°. At the beginning of next synodic month the true anomaly is going to be ∠135.6°.

Moon before apogee

10 days after point of apogee on 22 November 2009 at 20:07 in ♒ Aquarius. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next day, until the Moon reaches the point of next perigee on 4 December 2009 at 14:12 in ♋ Cancer.

Previous apogeeNext perigee

Distance to Moon 367 711 km

The Moon is 367 711 km (228 485 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 363 479 km (225 855 mi).

Moon before descending node

12 days after ascending node on 21 November 2009 at 11:34 in ♑ Capricorn. The Moon is located north of the ecliptic over the following day, until the lunar orbit crosses from North to South in descending node on 5 December 2009 at 03:18 in ♋ Cancer.

Draconic month

12 days since the beginning of current draconic month in ♑ Capricorn, the Moon is navigating from the beginning to the first part of the cycle.

Moon after northern standstill

1 day since the previous standstill on 2 December 2009 at 23:37 in ♊ Gemini when the Moon has reached North declination of ∠25.772°, the lunar orbit is extending southward over the next 12 days to face maximum declination of ∠-25.769° at the point of next southern standstill on 16 December 2009 at 02:38 in ♐ Sagittarius.

Previous standstillNext standstill

Syzygy in 13 days

In 13 days on 16 December 2009 at 12:02 in ♐ Sagittarius 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.
