First Quarter in Gemini

First Quarter on . Illuminated surface of the Moon is 50% and growing larger. Lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 5 March 2017 at 11:32 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 ∠15° of ♊ Gemini tropical zodiac sector.

Worm Moon after 7 days

Next Full Moon is the Worm Moon of March 2017 after 7 days on 12 March 2017 at 14:54.

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 ∠1970"

Lunar disc appears visually 1.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1970" and ∠1934".

Lunation 212 / 1165

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 212 of Meeus index or 1165 from Brown series.

Synodic month length 29.5 days

The length of this lunation is 29 days, 11 hours and 59 minutes and it is 2 hours and 40 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 45 minutes shorter than the mean synodic month length. It is 5 hours and 24 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠295°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠295° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠321.4°.

Moon after perigee

2 days since point of perigee on 3 March 2017 at 07:24 in ♉ Taurus the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 13 days until the Moon reaches the point of next apogee on 18 March 2017 at 17:25 in ♐ Sagittarius.

Distance to Moon 363 763 km

The Moon is 363 763 km (226 032 mi) away from Earth and getting further over the next 13 days until the point apogee when Earth-Moon distance is going to be 404 651 km (251 438 mi).

Moon before ascending node

7 days after descending node on 26 February 2017 at 06:28 in ♓ Pisces the Moon is positioned south of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from South to North in ascending node on 11 March 2017 at 04:17 in ♍ Virgo.

Moon before northern standstill

11 days since the last southern standstill on 21 February 2017 at 20:50 in ♑ Capricorn when the Moon has reached South declination of ∠-18.848° the lunar orbit is extending northward over the next day to face maximum declination of ∠18.861° at the point of next northern standstill on 7 March 2017 at 00:43 in ♋ Cancer.

Draconic month

21 days since the beginning of this draconic month in ♌ Leo the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 7 days

In 7 days on 12 March 2017 at 14:54 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.
