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 ♓ Pisces
Moon is leaving the last ∠4° of ♓ Pisces tropical zodiac sector and will enter ♈ Aries later.
Apparent angular diameter ∠1936"
Lunar disc appears visually 0.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1936" and ∠1950".
Cold Moon after 6 days
Next Full Moon is the Cold Moon of December 2007 after 6 days on 24 December 2007 at 01:16.
Upcoming main Moon phases
- Full Moon in Cancer ♋ on 24 December 2007 at 01:16
- Last Quarter in Libra ♎ on 31 December 2007 at 07:51
- New Moon in Capricorn ♑ on 8 January 2008 at 11:37

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 98 / 1051
The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 98 of Meeus index or 1051 from Brown series.
Synodic month length 29.75 days
The length of the lunation is 29 days, 17 hours and 57 minutes. It is 1 hour and 50 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 5 hours and 13 minutes longer than the mean synodic month length. It is 1 hour and 50 minutes shorter compared to 21st century's longest synodic month length.
Lunar orbit position on
True anomaly ∠209.6°
At the beginning of the lunation cycle the true anomaly is ∠209.6°. At the beginning of next synodic month the true anomaly is going to be ∠242.4°.
Moon before apogee
10 days after point of apogee on 6 December 2007 at 16:54 in ♏ Scorpio. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 4 days, until the Moon reaches the point of next perigee on 22 December 2007 at 10:11 in ♊ Gemini.
Distance to Moon 370 328 km
The Moon is 370 328 km (230 111 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 360 817 km (224 201 mi).
Moon after ascending node
1 day after ascending node on 15 December 2007 at 13:15 in ♒ Aquarius. The Moon is located north of the ecliptic over the following 10 days, until the lunar orbit crosses from North to South in descending node on 28 December 2007 at 02:57 in ♌ Leo.
Draconic month
1 day since the beginning of current draconic month in ♒ Aquarius, the Moon is navigating from the beginning to the first part of the cycle.
Moon before northern standstill
7 days since the previous standstill on 10 December 2007 at 09:41 in ♐ Sagittarius when the Moon has reached South declination of ∠-27.906°, the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠27.918° at the point of next northern standstill on 23 December 2007 at 14:26 in ♊ Gemini.
Syzygy in 6 days
In 6 days on 24 December 2007 at 01:16 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.
