Moon phase and lunation details

Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon is entering ♊ Gemini

Moon is passing first ∠3° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1784"

Lunar disc appears visually 8.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1784" and ∠1944".

Snow Moon after 6 days

Next Full Moon is the Snow Moon of February 2003 after 6 days on 16 February 2003 at 23:51.

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 38 / 991

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 38 of Meeus index or 991 from Brown series.

Synodic month length 29.66 days

The length of the lunation is 29 days, 15 hours and 47 minutes. It is 57 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the 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 3 hours and 3 minutes longer than the mean synodic month length. It is 4 hours shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠90.6°

At the beginning of the lunation cycle the true anomaly is ∠90.6°. At the beginning of next synodic month the true anomaly is going to be ∠127.8°.

Moon after apogee

2 days after point of apogee on 7 February 2003 at 21:58 in ♈ Aries. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 9 days, until the Moon reaches the point of next perigee on 19 February 2003 at 16:19 in ♍ Virgo.

Distance to Moon 401 829 km

The Moon is 401 829 km (249 685 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 364 844 km (226 704 mi).

Moon in ascending node

Moon is in ascending node in ♉ Taurus at 17:39 crossing the ecliptic from South to North to meet descending node 13 days later on 23 February 2003 at 15:47 in ♏ Scorpio.

New draconic month

At 17:39 the Moon completes the previous draconic month and enters the new one.

Moon before northern standstill

11 days since the previous standstill on 30 January 2003 at 00:31 in ♑ Capricorn when the Moon has reached South declination of ∠-25.834°, the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠25.923° at the point of next northern standstill on 13 February 2003 at 10:59 in ♋ Cancer.

Syzygy in 6 days

In 6 days on 16 February 2003 at 23:51 in ♌ Leo 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.
