First Quarter in Gemini

First Quarter on . Illuminated surface of the Moon is 53% and growing larger. Lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 28 February 2004 at 03:24 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 ∠13° of ♊ Gemini tropical zodiac sector.

Worm Moon after 7 days

Next Full Moon is the Worm Moon of March 2004 after 7 days on 6 March 2004 at 23:14.

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 ∠1768"

Lunar disc appears visually 9.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1937".

Lunation 51 / 1004

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 51 of Meeus index or 1004 from Brown series.

Synodic month length 29.56 days

The length of this lunation is 29 days, 13 hours and 24 minutes and it is 1 hour and 16 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 40 minutes longer than the mean synodic month length. It is 6 hours and 23 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠59.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠59.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠93.6°.

Moon at apogee

Moon is at apogee at 10:45 about 12 days since last perigee on 16 February 2004 at 07:34 in ♑ Capricorn the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 12 days until point of next perigee on 12 March 2004 at 03:37 in ♏ Scorpio.

Distance to Moon 404 259 km

This apogee Moon is 404 259 km (251 195 mi) away from Earth. This is the year's closest apogee of 2004. It is 1 149 km further than the mean apogee distance, but it is still 208 km closer than the farthest apogee of 21st century.

Moon after ascending node

2 days after ascending node on 26 February 2004 at 00:15 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 10 March 2004 at 23:05 in ♏ Scorpio.

Moon before northern standstill

11 days since the last southern standstill on 16 February 2004 at 13:51 in ♐ Sagittarius when the Moon has reached South declination of ∠-27.229° the lunar orbit is extending northward over the next day to face maximum declination of ∠27.341° at the point of next northern standstill on 1 March 2004 at 11:47 in ♋ Cancer.

Draconic month

2 days 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 7 days

In 7 days on 6 March 2004 at 23:14 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.
