First Quarter in Gemini

First Quarter on . Illuminated surface of the Moon is 56% and growing larger. Lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 12 February 2019 at 22:26 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 is entering ♊ Gemini

Moon is passing first ∠1° of ♊ Gemini tropical zodiac sector.

Snow Moon after 6 days

Next Full Moon is the Snow Moon of February 2019 after 6 days on 19 February 2019 at 15:53.

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 ∠1888"

Lunar disc appears visually 2.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1888" and ∠1943".

Lunation 236 / 1189

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 236 of Meeus index or 1189 from Brown series.

Synodic month length 29.79 days

The length of this lunation is 29 days, 19 hours and 1 minute and it is 2 hours and 13 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 longer than mean

The length of the current synodic month is 6 hours and 16 minutes longer than the mean synodic month length. It is 47 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠175.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠175.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠200.2°.

Moon before perigee

8 days since point of apogee on 5 February 2019 at 09:26 in ♒ Aquarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next perigee on 19 February 2019 at 09:06 in ♌ Leo.

Distance to Moon 379 569 km

The Moon is 379 569 km (235 853 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 356 762 km (221 682 mi).

Moon before ascending node

10 days after descending node on 3 February 2019 at 06:35 in ♑ Capricorn the Moon is positioned south of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from South to North in ascending node on 17 February 2019 at 09:42 in ♋ Cancer.

Moon before northern standstill

11 days since the last southern standstill on 2 February 2019 at 00:48 in ♑ Capricorn when the Moon has reached South declination of ∠-21.547° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠21.590° at the point of next northern standstill on 16 February 2019 at 09:56 in ♋ Cancer.

Draconic month

23 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 19 February 2019 at 15:53 in ♌ Leo 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.
