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 ∠3° of ♓ Pisces tropical zodiac sector and will enter ♈ Aries later.
Apparent angular diameter ∠1770"
Lunar disc appears visually 9.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1770" and ∠1951".
Cold Moon after 7 days
Next Full Moon is the Cold Moon of December 2001 after 7 days on 30 December 2001 at 10:41.
Upcoming main Moon phases

Neap tide
There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.
Lunation 24 / 977
The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 24 of Meeus index or 977 from Brown series.
Synodic month length 29.7 days
The length of the lunation is 29 days, 16 hours and 41 minutes. It is 1 hour and 31 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 3 hours and 57 minutes longer than the mean synodic month length. It is 3 hours and 6 minutes shorter compared to 21st century's longest synodic month length.
Lunar orbit position on
True anomaly ∠86.2°
At the beginning of the lunation cycle the true anomaly is ∠86.2°. At the beginning of next synodic month the true anomaly is going to be ∠123.9°.
Moon after apogee
1 day after point of apogee on 21 December 2001 at 13:02 in ♓ Pisces. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 10 days, until the Moon reaches the point of next perigee on 2 January 2002 at 07:13 in ♌ Leo.
Distance to Moon 404 908 km
The Moon is 404 908 km (251 598 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 365 412 km (227 056 mi).
Moon before ascending node
7 days after descending node on 15 December 2001 at 04:32 in ♐ Sagittarius. The Moon is located south of the ecliptic over the following 7 days, until the lunar orbit crosses from South to North in ascending node on 29 December 2001 at 14:51 in ♊ Gemini.
Draconic month
20 days since the beginning of current draconic month in ♊ Gemini, the Moon is navigating from the second to the final part of the cycle.
Moon after southern standstill
6 days since the previous standstill on 16 December 2001 at 07:51 in ♑ Capricorn when the Moon has reached South declination of ∠-24.250°, the lunar orbit is extending northward over the next 8 days to face maximum declination of ∠24.244° at the point of next northern standstill on 30 December 2001 at 15:40 in ♋ Cancer.
Syzygy in 7 days
In 7 days on 30 December 2001 at 10:41 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.
