Full Moon in Aries

Full Moon on . The illuminated surface of the moon is 100%. The lunar cycle is 14 days old.

* The exact date and time of this Full Moon phase is on 18 October 2100 at 04:06 UTC.

Moonrise and moonset

The moon rises at sunset and sets at sunrise. It is visible all night and it is high in the sky around midnight.

Moon phase and lunation details

Moon in ♈ Aries

Moon is passing about ∠17° of ♈ Aries tropical zodiac sector.

It is Hunter Moon

The Full Moon these days is the Hunter of October 2100.

Spring tide

There is high Full Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Earth-Moon syzygy alignment.

Apparent angular diameter ∠1779"

Lunar disc appears visually 7.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1779" and ∠1926".

Lunation 1246 / 2199

The Moon is 14 days old and navigating through the middle part of the current synodic month. This is lunation 1246 of Meeus index or 2199 from Brown series.

Synodic month length 29.38 days

The length of this lunation is 29 days, 9 hours and 12 minutes and it is 34 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2100. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length shorter than mean

The length of the current synodic month is 3 hours and 32 minutes shorter than the mean synodic month length. It is 2 hours and 37 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠340.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠340.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠356.4°.

Moon before apogee

12 days since point of perigee on 4 October 2100 at 21:58 in ♎ Libra the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next apogee on 20 October 2100 at 04:03 in ♉ Taurus.

Distance to Moon 402 964 km

The Moon is 402 964 km (250 390 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 406 359 km (252 500 mi).

Moon after ascending node

3 days after ascending node on 14 October 2100 at 06:36 in ♓ Pisces the Moon is positioned north of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from North to South in descending node on 28 October 2100 at 20:12 in ♌ Leo.

Moon before northern standstill

8 days since the last southern standstill on 8 October 2100 at 20:58 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.233° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠28.129° at the point of next northern standstill on 23 October 2100 at 08:12 in ♊ Gemini.

Draconic month

3 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the beginning to the first part of the lunar cycle.

Sun-Earth-Moon syzygy

The Moon is in a Full Moon geocentric opposition with the Sun and thus forming Sun-Earth-Moon syzygy alignment.
