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 19 February 2040 at 21:33 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 ∠8° of ♊ Gemini tropical zodiac sector.

Snow Moon after 7 days

Next Full Moon is the Snow Moon of February 2040 after 7 days on 28 February 2040 at 00:59.

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 ∠1780"

Lunar disc appears visually 8.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1780" and ∠1940".

Lunation 496 / 1449

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 496 of Meeus index or 1449 from Brown series.

Synodic month length 29.47 days

The length of this lunation is 29 days, 11 hours and 22 minutes and it is 52 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 shorter than mean

The length of the current synodic month is 1 hour and 22 minutes shorter than the mean synodic month length. It is 4 hours and 47 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠30.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠30.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠53.5°.

Moon before apogee

9 days since point of perigee on 10 February 2040 at 18:42 in ♑ Capricorn the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next apogee on 22 February 2040 at 15:18 in ♊ Gemini.

Distance to Moon 402 659 km

The Moon is 402 659 km (250 201 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 404 988 km (251 648 mi).

Moon in ascending node

Moon is in ascending node in ♊ Gemini at 14:18 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 5 March 2040 at 16:03 in ♐ Sagittarius.

Moon before northern standstill

10 days since the last southern standstill on 9 February 2040 at 16:13 in ♑ Capricorn when the Moon has reached South declination of ∠-25.560° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠25.645° at the point of next northern standstill on 23 February 2040 at 04:38 in ♋ Cancer.

New draconic month

At 14:18 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 7 days

In 7 days on 28 February 2040 at 00:59 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.
