Moon phase and lunation details

Moonrise and moonset

Moon rises at midnight and sets at noon. It is visible to the south in the morning.

Moon is entering ♊ Gemini

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

Apparent angular diameter ∠1768"

Lunar disc appears visually 7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1897".

Harvest Moon after 21 days

Next Full Moon is the Harvest Moon of September 2030 after 21 days on 11 September 2030 at 21:18.

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 378 / 1331

The Moon is 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 378 of Meeus index or 1331 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.5 days

Length of current 378 lunation is 29 days, 11 hours and 56 minutes. It is 1 hour and 9 minutes longer than next lunation 379 length.

Lunation length shorter than mean

Length of current synodic month is 48 minutes shorter than the mean length of synodic month, but it is still 5 hours and 21 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠244.5°

This lunation true anomaly is ∠244.5°. At the beginning of next synodic month true anomaly will be ∠279.9°. 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 22:49, this is 11 days after last perigee on 9 August 2030 at 22:50 in ♐ Sagittarius. Lunar orbit is starting to get closer, while the Moon is moving inward the Earth for 14 days ahead, until it will get to the point of next perigee on 4 September 2030 at 17:06 in ♐ Sagittarius.

Distance to Moon 404 174 km

This apogee Moon is 404 174 km (251 142 mi) away from Earth. This is the year's closest apogee of 2030. It is 1 234 km farther than the mean apogee distance, but it is still 123 km closer than the farthest apogee of 21st century.

Moon before descending node

12 days after its ascending node on 8 August 2030 at 19:44 in ♐ Sagittarius, the Moon is following the northern part of its orbit for the next day, until it will cross the ecliptic from North to South in descending node on 22 August 2030 at 08:09 in ♊ Gemini.

Draconic month

12 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the beginning to the first part of it.

Moon before northern standstill

12 days after previous South standstill on 9 August 2030 at 01:58 in ♐ Sagittarius, when Moon has reached southern declination of ∠-22.572°. Next day the lunar orbit moves northward to face North declination of ∠22.465° in the next northern standstill on 22 August 2030 at 18:22 in ♊ Gemini.

Syzygy in 7 days

After 7 days on 28 August 2030 at 23:07 in ♌ Leo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
