Moon is entering ♈ Aries

Moon is passing first ∠2° of ♈ Aries tropical zodiac sector.

Apparent angular diameter ∠1939"

Lunar disc appears visually 0.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1939" and ∠1951".

Next Full Moon is the Cold Moon of December 2069 after 6 days on 28 December 2069 at 00:50.

Upcoming main Moon phases

Synodic month length 29.74 days

The length of the lunation is 29 days, 17 hours and 45 minutes. It is 2 hours and 15 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 1 minute longer than the mean synodic month length. It is 2 hours and 2 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠211.5°

At the beginning of the lunation cycle the true anomaly is ∠211.5°. At the beginning of next synodic month the true anomaly is going to be ∠244.8°.

Moon before apogee

10 days after point of apogee on 10 December 2069 at 12:50 in ♏ Scorpio. 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 31 December 2069 at 15:07 in ♌ Leo.

Distance to Moon 369 753 km

The Moon is 369 753 km (229 754 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 370 337 km (230 117 mi).

Moon before descending node

11 days after ascending node on 9 December 2069 at 16:16 in ♎ Libra. The Moon is located north of the ecliptic over the following 2 days, until the lunar orbit crosses from North to South in descending node on 23 December 2069 at 17:14 in ♈ Aries.

Draconic month

11 days since the beginning of current draconic month in ♎ Libra, 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 13 December 2069 at 16:54 in ♐ Sagittarius when the Moon has reached South declination of ∠-19.339°, the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠19.319° at the point of next northern standstill on 27 December 2069 at 01:12 in ♊ Gemini.

Syzygy in 6 days

In 6 days on 28 December 2069 at 00:50 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.
