Full Moon in Aries

Full Moon on . The illuminated surface of the moon is 100%. The lunar cycle is 15 days old.

* The exact date and time of this Full Moon phase is on 29 September 2023 at 09:57 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 ∠7° of ♈ Aries tropical zodiac sector.

It is Harvest Moon

The Full Moon these days is the Harvest of September 2023.

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 ∠1951"

Lunar disc appears visually 1.8% wider than solar disc. Moon and Sun apparent angular diameters are ∠1951" and ∠1916".

Lunation 293 / 1246

The Moon is 15 days old and navigating through the middle part of the current synodic month. This is lunation 293 of Meeus index or 1246 from Brown series.

Synodic month length 29.68 days

The length of this lunation is 29 days, 16 hours and 15 minutes and it is 43 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2023. 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 longer than mean

The length of the current synodic month is 3 hours and 31 minutes longer than the mean synodic month length. It is 3 hours and 32 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠202.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠202.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠232.5°.

Moon after perigee

1 day since point of perigee on 28 September 2023 at 01:05 in ♓ Pisces the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next apogee on 10 October 2023 at 03:41 in ♌ Leo.

Distance to Moon 367 325 km

The Moon is 367 325 km (228 245 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 405 426 km (251 920 mi).

Moon before ascending node

11 days after descending node on 17 September 2023 at 19:18 in ♎ Libra the Moon is positioned south of the ecliptic over the following day until the lunar crosses the ecliptic again from South to North in ascending node on 30 September 2023 at 16:49 in ♈ Aries.

Moon after southern standstill

6 days since the last southern standstill on 23 September 2023 at 03:42 in ♑ Capricorn when the Moon has reached South declination of ∠-28.254° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠28.294° at the point of next northern standstill on 5 October 2023 at 20:31 in ♊ Gemini.

Draconic month

26 days since the beginning of this draconic month in ♈ Aries the Moon is navigating from the second to the final 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.
