First Quarter in Gemini

First Quarter on . Illuminated surface of the Moon is 48% and growing larger. Lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 1 March 2077 at 16:11 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 ♊ Gemini

Moon is passing about ∠9° of ♊ Gemini tropical zodiac sector.

Worm Moon after 8 days

Next Full Moon is the Worm Moon of March 2077 after 8 days on 9 March 2077 at 17:42.

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 ∠1878"

Lunar disc appears visually 3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1878" and ∠1936".

Lunation 954 / 1907

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 954 of Meeus index or 1907 from Brown series.

Synodic month length 29.39 days

The length of this lunation is 29 days, 9 hours and 18 minutes and it is 22 minutes longer 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 shorter than mean

The length of the current synodic month is 3 hours and 26 minutes shorter than the mean synodic month length. It is 2 hours and 43 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠355.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠355.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠10.8°.

Moon after perigee

6 days since point of perigee on 23 February 2077 at 05:20 in ♓ Pisces the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next apogee on 9 March 2077 at 03:31 in ♍ Virgo.

Distance to Moon 381 666 km

The Moon is 381 666 km (237 156 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 406 511 km (252 594 mi).

Moon in ascending node

Moon is in ascending node in ♊ Gemini at 17:53 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 14 days until Moon's next descending node later on 16 March 2077 at 09:32 in ♐ Sagittarius.

Moon before northern standstill

10 days since the last southern standstill on 19 February 2077 at 06:40 in ♑ Capricorn when the Moon has reached South declination of ∠-25.259° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠25.349° at the point of next northern standstill on 3 March 2077 at 22:10 in ♋ Cancer.

New draconic month

At 17:53 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 8 days

In 8 days on 9 March 2077 at 17:42 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.
