Moon phase and lunation details

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 20 August 2003 at 00:48.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon in ♊ Gemini

Moon is passing about ∠14° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1776"

Lunar disc appears visually 6.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1776" and ∠1897".

Harvest Moon after 20 days

Next Full Moon is the Harvest Moon of September 2003 after 20 days on 10 September 2003 at 16:36.

Upcoming main Moon phases

Neap tide

There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

Lunation 44 / 997

The Moon is 23 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 44 of Meeus index or 997 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.44 days

The length of the lunation is 29 days, 10 hours and 34 minutes. It is 51 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the 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 2 hours and 10 minutes shorter than the mean synodic month length. It is 3 hours and 59 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠268.5°

At the beginning of the lunation cycle the true anomaly is ∠268.5°. At the beginning of next synodic month the true anomaly is going to be ∠301°.

Moon after apogee

1 day after point of apogee on 19 August 2003 at 14:22 in ♉ Taurus. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 10 days, until the Moon reaches the point of next perigee on 31 August 2003 at 18:47 in ♎ Libra.

Previous apogeeNext perigee

Distance to Moon 403 611 km

The Moon is 403 611 km (250 792 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 367 929 km (228 620 mi).

Moon after ascending node

1 day after ascending node on 19 August 2003 at 21:08 in ♉ Taurus. The Moon is located north of the ecliptic over the following 11 days, until the lunar orbit crosses from North to South in descending node on 2 September 2003 at 07:23 in ♏ Scorpio.

Draconic month

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

Moon before northern standstill

12 days since the previous standstill on 9 August 2003 at 06:19 in ♑ Capricorn when the Moon has reached South declination of ∠-26.553°, the lunar orbit is extending northward over the next day to face maximum declination of ∠26.649° at the point of next northern standstill on 23 August 2003 at 11:41 in ♋ Cancer.

Syzygy in 6 days

In 6 days on 27 August 2003 at 17:26 in ♌ Leo the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
