First Quarter in Aries

First Quarter on . The illuminated surface of the moon is 48% and growing larger. The lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 10 January 2098 at 16:58 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 ♈ Aries

Moon is passing about ∠18° of ♈ Aries tropical zodiac sector.

Wolf Moon after 6 days

Next Full Moon is the Wolf Moon of January 2098 after 6 days on 17 January 2098 at 10:36.

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 ∠1864"

Lunar disc appears visually 4.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1864" and ∠1951".

Lunation 1212 / 2165

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 1212 of Meeus index or 2165 from Brown series.

Synodic month length 29.81 days

The length of this lunation is 29 days, 19 hours and 22 minutes and it is 1 hour and 14 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2098. 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 6 hours and 38 minutes longer than the mean synodic month length. It is 25 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠172.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠172.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠197°.

Moon before perigee

7 days since point of apogee on 3 January 2098 at 11:59 in ♑ Capricorn the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next perigee on 17 January 2098 at 06:41 in ♋ Cancer.

Distance to Moon 384 595 km

The Moon is 384 595 km (238 976 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 356 435 km (221 478 mi).

Moon before ascending node

13 days after descending node on 27 December 2097 at 16:48 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 11 January 2098 at 08:24 in ♈ Aries.

Moon before northern standstill

8 days since the last southern standstill on 1 January 2098 at 23:06 in ♐ Sagittarius when the Moon has reached South declination of ∠-27.839° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠27.895° at the point of next northern standstill on 15 January 2098 at 22:37 in ♊ Gemini.

Draconic month

26 days since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 6 days

In 6 days on 17 January 2098 at 10:36 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.
