First Quarter in Aries

First Quarter on . Illuminated surface of the Moon is 55% and growing larger. Lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 9 January 2090 at 01:21 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 ♈ Aries

Moon is passing about ∠25° of ♈ Aries tropical zodiac sector.

Wolf Moon after 6 days

Next Full Moon is the Wolf Moon of January 2090 after 6 days on 16 January 2090 at 03:02.

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Apparent angular diameter ∠1816"

Lunar disc appears visually 7.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1816" and ∠1951".

Lunation 1113 / 2066

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 1113 of Meeus index or 2066 from Brown series.

Synodic month length 29.78 days

The length of this lunation is 29 days, 18 hours and 37 minutes and it is 35 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 longer than mean

The length of the current synodic month is 5 hours and 53 minutes longer than the mean synodic month length. It is 1 hour and 10 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠135.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠135.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠163.9°.

Moon after apogee

4 days since point of apogee on 4 January 2090 at 23:25 in ♒ Aquarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next perigee on 17 January 2090 at 04:55 in ♌ Leo.

Distance to Moon 394 591 km

The Moon is 394 591 km (245 187 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 358 708 km (222 891 mi).

Moon after descending node

1 day after descending node on 7 January 2090 at 17:09 in ♓ Pisces the Moon is positioned south of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from South to North in ascending node on 20 January 2090 at 12:25 in ♎ Libra.

Moon before northern standstill

9 days since the last southern standstill on 30 December 2089 at 21:23 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.450° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠18.390° at the point of next northern standstill on 14 January 2090 at 07:41 in ♊ Gemini.

Draconic month

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

Syzygy in 6 days

In 6 days on 16 January 2090 at 03:02 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.
