Moon phase and lunation details

5 days after Full Moon

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 ♒ Aquarius

Moon is passing about ∠12° of ♒ Aquarius tropical zodiac sector.

Apparent angular diameter ∠1870"

Lunar disc appears visually 1.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1870" and ∠1896".

Flower Moon before 5 days

Next Full Moon is the Strawberry Moon of June 2003 after 23 days on 14 June 2003 at 11:16.

Upcoming main Moon phases

  • Last Quarter in Pisces ♓ on 23 May 2003 at 00:31

  • Full Moon in Sagittarius ♐ on 14 June 2003 at 11:16

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 41 / 994

The Moon is 20 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 41 of Meeus index or 994 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.67 days

Length of current 41 lunation is 29 days, 16 hours and 5 minutes. It is 1 hour and 46 minutes longer than next lunation 42 length.

Lunation length longer than mean

Length of current synodic month is 3 hours and 21 minutes longer than the mean length of synodic month, but it is still 3 hours and 42 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠181.7°

This lunation true anomaly is ∠181.7°. At the beginning of next synodic month true anomaly will be ∠205.5°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).

Moon after perigee

5 days after point of perigee on 15 May 2003 at 15:39 in ♏ Scorpio. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 7 days, until it get to the point of next apogee on 28 May 2003 at 13:05 in ♉ Taurus.

Previous perigeeNext apogee

Distance to Moon 383 266 km

Moon is 383 266 km (238 150 mi) away from Earth on this date. Moon moves farther next 7 days until apogee, when Earth-Moon distance will reach 406 171 km (252 383 mi).

Moon after descending node

5 days after its descending node on 16 May 2003 at 10:51 in ♏ Scorpio, the Moon is following the southern part of its orbit for the next 8 days, until it will cross the ecliptic from South to North in ascending node on 30 May 2003 at 08:33 in ♉ Taurus.

Draconic month

18 days after beginning of current draconic month in ♉ Taurus, the Moon is moving from the second to the final part of it.

Moon after southern standstill

2 days after previous South standstill on 19 May 2003 at 03:13 in ♑ Capricorn, when Moon has reached southern declination of ∠-26.503°. Next 12 days the lunar orbit moves northward to face North declination of ∠26.491° in the next northern standstill on 2 June 2003 at 15:27 in ♋ Cancer.

Syzygy in 9 days

After 9 days on 31 May 2003 at 04:20 in ♊ Gemini, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
