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 15 March 2016 at 17:03 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 ∠23° of ♊ Gemini tropical zodiac sector.

Worm Moon after 8 days

Next Full Moon is the Worm Moon of March 2016 after 8 days on 23 March 2016 at 12:01.

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 ∠1923"

Lunar disc appears visually 0.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1923" and ∠1929".

Lunation 200 / 1153

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 200 of Meeus index or 1153 from Brown series.

Synodic month length 29.4 days

The length of this lunation is 29 days, 9 hours and 29 minutes and it is 1 hour and 23 minutes 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 shorter than mean

The length of the current synodic month is 3 hours and 15 minutes shorter than the mean synodic month length. It is 2 hours and 54 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠339.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠339.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠355.6°.

Moon after perigee

5 days since point of perigee on 10 March 2016 at 07:02 in ♈ Aries the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next apogee on 25 March 2016 at 14:16 in ♎ Libra.

Distance to Moon 372 816 km

The Moon is 372 816 km (231 657 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 406 125 km (252 354 mi).

Moon after descending node

6 days after descending node on 9 March 2016 at 06:31 in ♓ Pisces the Moon is positioned south of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from South to North in ascending node on 22 March 2016 at 12:59 in ♍ Virgo.

Moon before northern standstill

11 days since the last southern standstill on 3 March 2016 at 14:19 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.210° the lunar orbit is extending northward over the next day to face maximum declination of ∠18.206° at the point of next northern standstill on 16 March 2016 at 05:01 in ♋ Cancer.

Draconic month

20 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 8 days

In 8 days on 23 March 2016 at 12:01 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.
