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 ∠13° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1768"

Lunar disc appears visually 6.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1888".

Sturgeon Moon after 17 days

Next Full Moon is the Sturgeon Moon of August 2039 after 17 days on 4 August 2039 at 09:56.

Upcoming main Moon phases

  • New Moon in Cancer ♋ on 21 July 2039 at 07:54
  • First Quarter in Libra ♎ on 28 July 2039 at 17:50

  • Last Quarter in Taurus ♉ on 11 August 2039 at 19:36

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 488 / 1441

The Moon is 26 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 488 of Meeus index or 1441 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.61 days

Length of current 488 lunation is 29 days, 14 hours and 33 minutes. It is 1 hour and 37 minutes longer than next lunation 489 length.

Lunation length longer than mean

Length of current synodic month is 1 hour and 49 minutes longer than the mean length of synodic month, but it is still 5 hours and 14 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠199.2°

This lunation true anomaly is ∠199.2°. At the beginning of next synodic month true anomaly will be ∠226.3°. 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 in apogee

Moon is reaching point of apogee on this date at 03:14, this is 12 days after last perigee on 4 July 2039 at 20:31 in ♐ Sagittarius. Lunar orbit is starting to get closer, while the Moon is moving inward the Earth for 15 days ahead, until it will get to the point of next perigee on 1 August 2039 at 22:38 in ♐ Sagittarius.

Previous perigeeNext perigee

Distance to Moon 405 452 km

This apogee Moon is 405 452 km (251 936 mi) away from Earth. It is 44 km farther than the mean apogee distance, but it is still 1 257 km closer than the farthest apogee of 21st century.

Moon before ascending node

12 days after its descending node on 4 July 2039 at 14:57 in ♐ Sagittarius, the Moon is following the southern part of its orbit for the next day, until it will cross the ecliptic from South to North in ascending node on 18 July 2039 at 06:48 in ♊ Gemini.

Draconic month

26 days after beginning of current draconic month in ♊ Gemini, the Moon is moving from the second to the final part of it.

Moon before northern standstill

11 days after previous South standstill on 5 July 2039 at 22:01 in ♑ Capricorn, when Moon has reached southern declination of ∠-24.696°. Next 2 days the lunar orbit moves northward to face North declination of ∠24.697° in the next northern standstill on 19 July 2039 at 22:01 in ♋ Cancer.

Syzygy in 3 days

After 3 days on 21 July 2039 at 07:54 in ♋ Cancer, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
