First Quarter in Gemini

First Quarter on . The illuminated surface of the moon is 63% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 3 March 2039 at 02:15 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 ∠1° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.

Worm Moon after 6 days

Next Full Moon is the Worm Moon of March 2039 after 6 days on 10 March 2039 at 16:35.

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 ∠1783"

Lunar disc appears visually 8.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1783" and ∠1935".

Lunation 484 / 1437

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 484 of Meeus index or 1437 from Brown series.

Synodic month length 29.61 days

The length of this lunation is 29 days, 14 hours and 42 minutes and it is 53 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 1 hour and 58 minutes longer than the mean synodic month length. It is 5 hours and 5 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠83.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠83.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠120.7°.

Moon after apogee

2 days since point of apogee on 1 March 2039 at 22:42 in ♉ Taurus the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next perigee on 13 March 2039 at 18:38 in ♎ Libra.

Distance to Moon 402 011 km

The Moon is 402 011 km (249 798 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 366 000 km (227 422 mi).

Moon in ascending node

Moon is in ascending node in ♊ Gemini at 09:49 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 12 days until Moon's next descending node later on 17 March 2039 at 10:05 in ♐ Sagittarius.

Moon before northern standstill

13 days since the last southern standstill on 19 February 2039 at 06:19 in ♑ Capricorn when the Moon has reached South declination of ∠-24.002° the lunar orbit is extending northward over the next day to face maximum declination of ∠24.115° at the point of next northern standstill on 5 March 2039 at 12:11 in ♋ Cancer.

New draconic month

At 09:49 in the point ot ascending node the Moon is completing the last draconic month and is entering a new one while the lunar orbit is crossing the ecliptic from South to North.

Syzygy in 6 days

In 6 days on 10 March 2039 at 16:35 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.
