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 ♐ Sagittarius

Moon is passing about ∠6° of ♐ Sagittarius tropical zodiac sector.

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 387 / 1340

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 387 of Meeus index or 1340 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.6 days

Length of current 387 lunation is 29 days, 14 hours and 20 minutes. It is 47 minutes shorter than next lunation 388 length.

Lunation length longer than mean

Length of current synodic month is 1 hour and 36 minutes longer than the mean length of synodic month, but it is still 5 hours and 27 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠106.4°

This New Moon true anomaly is ∠106.4°. At beginning of next synodic month true anomaly will be ∠139.8°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon before perigee

11 days after point of apogee on 27 April 2031 at 10:30 in ♋ Cancer. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next day, until it get to the point of next perigee on 9 May 2031 at 07:28 in ♐ Sagittarius.

Previous apogeeNext perigee

Distance to Moon 366 426 km

Moon is 366 426 km (227 687 mi) away from Earth on this date. Moon moves closer next day until perigee, when Earth-Moon distance will reach 362 851 km (225 465 mi).

Moon after ascending node

1 day after its ascending node on 7 May 2031 at 22:55 in ♏ Scorpio, the Moon is following the northern part of its orbit for the next 12 days, until it will cross the ecliptic from North to South in descending node on 21 May 2031 at 03:26 in ♉ Taurus.

Draconic month

1 day after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the beginning to the first part of it.

Moon before southern standstill

12 days after previous North standstill on 25 April 2031 at 12:37 in ♊ Gemini, when Moon has reached northern declination of ∠21.107°. Next day the lunar orbit moves southward to face South declination of ∠-21.092° in the next southern standstill on 9 May 2031 at 07:56 in ♐ Sagittarius.

Syzygy in 12 days

After 12 days on 21 May 2031 at 07:17 in ♊ Gemini, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
