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 in ♉ Taurus

Moon is passing about ∠8° of ♉ Taurus tropical zodiac sector.

Apparent angular diameter ∠1776"

Lunar disc appears visually 6.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1776" and ∠1890".

Sturgeon Moon after 22 days

Next Full Moon is the Sturgeon Moon of August 2021 after 22 days on 22 August 2021 at 12:02.

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 266 / 1219

The Moon is 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 266 of Meeus index or 1219 from Brown series.

Synodic month length 29.52 days

Length of current 266 lunation is 29 days, 12 hours and 34 minutes. It is 1 hour and 32 minutes longer than next lunation 267 length.

Lunation length shorter than mean

Length of current synodic month is 11 minutes shorter than the mean length of synodic month, but it is still 5 hours and 59 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠230.1°

This lunation true anomaly is ∠230.1°. At the beginning of next synodic month true anomaly will be ∠264.3°. 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 before apogee

10 days after point of perigee on 21 July 2021 at 10:30 in ♐ Sagittarius. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next day, until it get to the point of next apogee on 2 August 2021 at 07:35 in ♉ Taurus.

Distance to Moon 403 587 km

Moon is 403 587 km (250 777 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 404 412 km (251 290 mi).

Moon before ascending node

10 days after its descending node on 20 July 2021 at 13:22 in ♐ Sagittarius, the Moon is following the southern part of its orbit for the next 2 days, until it will cross the ecliptic from South to North in ascending node on 3 August 2021 at 02:51 in ♊ Gemini.

Draconic month

24 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

8 days after previous South standstill on 22 July 2021 at 15:11 in ♑ Capricorn, when Moon has reached southern declination of ∠-25.643°. Next 5 days the lunar orbit moves northward to face North declination of ∠25.685° in the next northern standstill on 5 August 2021 at 16:46 in ♋ Cancer.

Syzygy in 8 days

After 8 days on 8 August 2021 at 13:50 in ♌ Leo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
