First Quarter in Gemini

First Quarter on . Illuminated surface of the Moon is 52% and growing larger. Lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 11 March 2003 at 07:15 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 ∠23° of ♊ Gemini tropical zodiac sector.

Worm Moon after 6 days

Next Full Moon is the Worm Moon of March 2003 after 6 days on 18 March 2003 at 10:34.

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 ∠1803"

Lunar disc appears visually 6.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1803" and ∠1931".

Lunation 39 / 992

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 39 of Meeus index or 992 from Brown series.

Synodic month length 29.7 days

The length of this lunation is 29 days, 16 hours and 44 minutes and it is 12 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 longer than mean

The length of the current synodic month is 4 hours longer than the mean synodic month length. It is 3 hours and 3 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠127.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠127.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠157.7°.

Moon after apogee

3 days since point of apogee on 7 March 2003 at 16:34 in ♉ Taurus the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next perigee on 19 March 2003 at 18:57 in ♎ Libra.

Distance to Moon 397 486 km

The Moon is 397 486 km (246 986 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 359 818 km (223 581 mi).

Moon after ascending node

1 day after ascending node on 9 March 2003 at 19:23 in ♉ Taurus the Moon is positioned north of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from North to South in descending node on 22 March 2003 at 17:37 in ♏ Scorpio.

Moon before northern standstill

13 days since the last southern standstill on 26 February 2003 at 05:53 in ♑ Capricorn when the Moon has reached South declination of ∠-26.015° the lunar orbit is extending northward over the next day to face maximum declination of ∠26.158° at the point of next northern standstill on 12 March 2003 at 19:44 in ♋ Cancer.

Draconic month

1 day since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 6 days

In 6 days on 18 March 2003 at 10:34 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.
