First Quarter in Capricorn

First Quarter on . The illuminated surface of the moon is 45% and growing larger. The lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 20 October 2099 at 23:27 UTC.

Moonrise and moonset

The moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon phase and lunation details

Moon in ♑ Capricorn

Moon is passing about ∠22° of ♑ Capricorn tropical zodiac sector.

Hunter Moon after 8 days

Next Full Moon is the Hunter Moon of October 2099 after 8 days on 29 October 2099 at 04:20.

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.

Apparent angular diameter ∠1839"

Lunar disc appears visually 4.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1839" and ∠1928".

Lunation 1234 / 2187

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 1234 of Meeus index or 2187 from Brown series.

Synodic month length 29.41 days

The length of this lunation is 29 days, 9 hours and 57 minutes and it is 1 hour and 43 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length shorter than mean

The length of the current synodic month is 2 hours and 47 minutes shorter than the mean synodic month length. It is 3 hours and 22 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠10.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠10.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠27.7°.

Moon before apogee

7 days since point of perigee on 13 October 2099 at 10:26 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 5 days until the Moon reaches the point of next apogee on 26 October 2099 at 03:06 in ♓ Pisces.

Distance to Moon 389 779 km

The Moon is 389 779 km (242 197 mi) away from Earth and getting further over the next 5 days until the point apogee when Earth-Moon distance is going to be 405 825 km (252 168 mi).

Moon before ascending node

8 days after descending node on 12 October 2099 at 10:42 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from South to North in ascending node on 25 October 2099 at 20:01 in ♓ Pisces.

Moon after southern standstill

1 day since the last southern standstill on 18 October 2099 at 19:06 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.609° the lunar orbit is extending northward over the next 12 days to face maximum declination of ∠28.524° at the point of next northern standstill on 2 November 2099 at 11:20 in ♊ Gemini.

Draconic month

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

Syzygy in 8 days

In 8 days on 29 October 2099 at 04:20 in ♉ Taurus 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.
