Moon phase and lunation details

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 1 August 2099 at 02:59.

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 ♈ Aries

Moon is passing about ∠13° of ♈ Aries tropical zodiac sector.

Apparent angular diameter ∠1772"

Lunar disc appears visually 6.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1772" and ∠1892".

Sturgeon Moon before 5 days

Next Full Moon is the Sturgeon Moon of August 2099 after 24 days on 30 August 2099 at 17:56.

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 1231 / 2184

The Moon is 19 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 1231 of Meeus index or 2184 from Brown series.

Synodic month length 29.33 days

Length of current 1231 lunation is 29 days, 7 hours and 54 minutes. This is the year's shortest synodic month of 2099. It is 2 minutes shorter than next lunation 1232 length.

Lunation length shorter than mean

Length of current synodic month is 4 hours and 50 minutes shorter than the mean length of synodic month, but it is still 1 hour and 19 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠320.2°

This lunation true anomaly is ∠320.2°. At the beginning of next synodic month true anomaly will be ∠339.4°. 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 after apogee

1 day after point of apogee on 5 August 2099 at 08:15 in ♓ Pisces. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 11 days, until it get to the point of next perigee on 17 August 2099 at 14:24 in ♍ Virgo.

Previous apogeeNext perigee

Distance to Moon 404 456 km

Moon is 404 456 km (251 317 mi) away from Earth on this date. Moon moves closer next 11 days until perigee, when Earth-Moon distance will reach 359 644 km (223 472 mi).

Moon after ascending node

1 day after its ascending node on 5 August 2099 at 03:00 in ♓ Pisces, 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 18 August 2099 at 13:42 in ♍ Virgo.

Draconic month

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

Moon before northern standstill

8 days after previous South standstill on 28 July 2099 at 23:58 in ♐ Sagittarius, when Moon has reached southern declination of ∠-28.504°. Next 6 days the lunar orbit moves northward to face North declination of ∠28.579° in the next northern standstill on 12 August 2099 at 14:22 in ♊ Gemini.

Syzygy in 9 days

After 9 days on 16 August 2099 at 08:54 in ♌ Leo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
