First Quarter in Aquarius

First Quarter on . Illuminated surface of the Moon is 60% and growing larger. Lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 23 October 2020 at 13:23 UTC.

Moonrise and moonset

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

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♒ Aquarius

Moon is passing about ∠13° of ♒ Aquarius tropical zodiac sector.

Hunter Moon after 7 days

Next Full Moon is the Hunter Moon of October 2020 after 7 days on 31 October 2020 at 14:49.

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 ∠1847"

Lunar disc appears visually 4.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1847" and ∠1930".

Lunation 257 / 1210

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 257 of Meeus index or 1210 from Brown series.

Synodic month length 29.4 days

The length of this lunation is 29 days, 9 hours and 36 minutes and it is 1 hour and 33 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 3 hours and 8 minutes shorter than the mean synodic month length. It is 3 hours and 1 minute longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠357°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠357° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠12.4°.

Moon before apogee

7 days since point of perigee on 16 October 2020 at 23:46 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 6 days until the Moon reaches the point of next apogee on 30 October 2020 at 18:46 in ♈ Aries.

Distance to Moon 388 060 km

The Moon is 388 060 km (241 129 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 406 393 km (252 521 mi).

Moon after descending node

3 days after descending node on 20 October 2020 at 15:53 in ♐ Sagittarius the Moon is positioned south of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from South to North in ascending node on 4 November 2020 at 02:39 in ♊ Gemini.

Moon after southern standstill

2 days since the last southern standstill on 22 October 2020 at 02:00 in ♑ Capricorn when the Moon has reached South declination of ∠-24.708° the lunar orbit is extending northward over the next 12 days to face maximum declination of ∠24.813° at the point of next northern standstill on 5 November 2020 at 19:30 in ♋ Cancer.

Draconic month

16 days since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 7 days

In 7 days on 31 October 2020 at 14:49 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.
