Moon phase and lunation details

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 10 September 2003 at 16:36.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon in ♈ Aries

Moon is passing about ∠10° of ♈ Aries tropical zodiac sector.

Apparent angular diameter ∠1796"

Lunar disc appears visually 6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1796" and ∠1907".

Harvest Moon before 1 day

Next Full Moon is the Hunter Moon of October 2003 after 27 days on 10 October 2003 at 07:27.

Upcoming main Moon phases

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.

Lunation 45 / 998

The Moon is 16 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 45 of Meeus index or 998 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.4 days

The length of the lunation is 29 days, 9 hours and 43 minutes. It is 2 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 3 hours and 1 minute shorter than the mean synodic month length. It is 3 hours and 8 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠301°

At the beginning of the lunation cycle the true anomaly is ∠301°. At the beginning of next synodic month the true anomaly is going to be ∠325.5°.

Moon before perigee

11 days after point of perigee on 31 August 2003 at 18:47 in ♎ Libra. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 3 days, until the Moon reaches the point of next apogee on 16 September 2003 at 09:22 in ♉ Taurus.

Previous perigeeNext apogee

Distance to Moon 399 174 km

The Moon is 399 174 km (248 035 mi) away from Earth and getting further over the next 3 days until the point apogee when Earth-Moon distance is going to be 404 713 km (251 477 mi).

Moon before ascending node

10 days after descending node on 2 September 2003 at 07:23 in ♏ Scorpio. The Moon is located south of the ecliptic over the following 3 days, until the lunar orbit crosses from South to North in ascending node on 15 September 2003 at 23:28 in ♉ Taurus.

Draconic month

23 days since the beginning of current draconic month in ♉ Taurus, the Moon is navigating from the second to the final part of the cycle.

Moon after southern standstill

7 days since the previous standstill on 5 September 2003 at 11:54 in ♑ Capricorn when the Moon has reached South declination of ∠-26.746°, the lunar orbit is extending northward over the next 7 days to face maximum declination of ∠26.874° at the point of next northern standstill on 19 September 2003 at 19:56 in ♋ Cancer.

Syzygy in 13 days

In 13 days on 26 September 2003 at 03:09 in ♎ Libra 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.
