First Quarter in Gemini

First Quarter on . The illuminated surface of the moon is 54% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 14 March 2038 at 03:42 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 leaving the last ∠2° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.

Worm Moon after 6 days

Next Full Moon is the Worm Moon of March 2038 after 6 days on 21 March 2038 at 02:09.

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 ∠1835"

Lunar disc appears visually 5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1835" and ∠1930".

Lunation 472 / 1425

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 472 of Meeus index or 1425 from Brown series.

Synodic month length 29.73 days

The length of this lunation is 29 days, 17 hours and 28 minutes and it is 51 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2038. 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 4 hours and 44 minutes longer than the mean synodic month length. It is 2 hours and 19 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠149.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠149.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠175.3°.

Moon after apogee

5 days since point of apogee on 9 March 2038 at 00:39 in ♈ Aries 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 21 March 2038 at 17:16 in ♎ Libra.

Distance to Moon 390 553 km

The Moon is 390 553 km (242 678 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 357 387 km (222 070 mi).

Moon before ascending node

13 days after descending node on 1 March 2038 at 08:52 in ♑ Capricorn 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 15 March 2038 at 23:29 in ♋ Cancer.

Moon before northern standstill

13 days since the last southern standstill on 28 February 2038 at 20:34 in ♑ Capricorn when the Moon has reached South declination of ∠-22.311° the lunar orbit is extending northward over the next day to face maximum declination of ∠22.441° at the point of next northern standstill on 15 March 2038 at 13:46 in ♋ Cancer.

Draconic month

25 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 6 days

In 6 days on 21 March 2038 at 02:09 in ♎ Libra 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.
