Moon phase and lunation details

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 11 August 2039 at 19:36.

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 ∠9° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1768"

Lunar disc appears visually 6.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1894".

Harvest Moon after 20 days

Next Full Moon is the Harvest Moon of September 2039 after 20 days on 2 September 2039 at 19:23.

Upcoming main Moon phases

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 489 / 1442

The Moon is 23 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 489 of Meeus index or 1442 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.54 days

Length of current 489 lunation is 29 days, 12 hours and 56 minutes. It is 1 hour and 24 minutes longer than next lunation 490 length.

Lunation length longer than mean

Length of current synodic month is 12 minutes longer than the mean length of synodic month, but it is still 6 hours and 51 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠226.3°

This lunation true anomaly is ∠226.3°. At the beginning of next synodic month true anomaly will be ∠260.1°. 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 19:35, this is 11 days after last perigee on 1 August 2039 at 22:38 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 29 August 2039 at 03:16 in ♑ Capricorn.

Distance to Moon 404 503 km

This apogee Moon is 404 503 km (251 347 mi) away from Earth. It is 905 km farther than the mean apogee distance, but it is still 2 206 km closer than the farthest apogee of 21st century.

Moon before ascending node

12 days after its descending node on 31 July 2039 at 22:26 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 14 August 2039 at 10:57 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 2 August 2039 at 07:15 in ♑ Capricorn, when Moon has reached southern declination of ∠-24.732°. Next 2 days the lunar orbit moves northward to face North declination of ∠24.786° in the next northern standstill on 16 August 2039 at 04:38 in ♋ Cancer.

Syzygy in 6 days

After 6 days on 19 August 2039 at 20:50 in ♌ Leo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
