First Quarter in Gemini

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 March 2098 at 16:01 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 ♊ Gemini

Moon is passing about ∠18° of ♊ Gemini tropical zodiac sector.

Worm Moon after 6 days

Next Full Moon is the Worm Moon of March 2098 after 6 days on 17 March 2098 at 07:43.

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 ∠1949"

Lunar disc appears visually 0.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1949" and ∠1931".

Lunation 1214 / 2167

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 1214 of Meeus index or 2167 from Brown series.

Synodic month length 29.66 days

The length of this lunation is 29 days, 15 hours and 45 minutes and it is 3 hours longer than the upcoming lunation's length. 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 1 minute longer than the mean synodic month length. It is 4 hours and 2 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠225.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠225.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠260.4°.

Moon before perigee

11 days since point of apogee on 27 February 2098 at 00:05 in ♑ Capricorn the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 4 days until the Moon reaches the point of next perigee on 14 March 2098 at 23:15 in ♌ Leo.

Distance to Moon 367 842 km

The Moon is 367 842 km (228 566 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 363 603 km (225 932 mi).

Moon after ascending node

4 days after ascending node on 6 March 2098 at 10:58 in ♈ Aries the Moon is positioned north of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from North to South in descending node on 19 March 2098 at 05:21 in ♎ Libra.

Moon before northern standstill

13 days since the last southern standstill on 25 February 2098 at 10:08 in ♑ Capricorn when the Moon has reached South declination of ∠-28.136° the lunar orbit is extending northward over the next day to face maximum declination of ∠28.231° at the point of next northern standstill on 11 March 2098 at 15:13 in ♊ Gemini.

Draconic month

4 days since the beginning of this draconic month in ♈ Aries the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 6 days

In 6 days on 17 March 2098 at 07:43 in ♍ Virgo 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.
