Moon phase and lunation details

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 27 September 2091 at 15:56.

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 ♉ Taurus

Moon is passing about ∠9° of ♉ Taurus tropical zodiac sector.

Apparent angular diameter ∠1768"

Lunar disc appears visually 8.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1917".

Harvest Moon before 2 days

Next Full Moon is the Hunter Moon of October 2091 after 26 days on 27 October 2091 at 09:18.

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 1134 / 2087

The Moon is 17 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 1134 of Meeus index or 2087 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.37 days

Length of current 1134 lunation is 29 days, 8 hours and 54 minutes. This is the year's shortest synodic month of 2091. It is 19 minutes shorter than next lunation 1135 length.

Lunation length shorter than mean

Length of current synodic month is 3 hours and 50 minutes shorter than the mean length of synodic month, but it is still 2 hours and 19 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠332.3°

This lunation true anomaly is ∠332.3°. At the beginning of next synodic month true anomaly will be ∠349.5°. 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 16:41, this is 15 days after last perigee on 15 September 2091 at 01:40 in ♎ Libra. Lunar orbit is starting to get closer, while the Moon is moving inward the Earth for 12 days ahead, until it will get to the point of next perigee on 13 October 2091 at 09:20 in ♎ Libra.

Previous perigeeNext perigee

Distance to Moon 406 084 km

This apogee Moon is 406 084 km (252 329 mi) away from Earth. It is 676 km farther than the mean apogee distance, but it is still 625 km closer than the farthest apogee of 21st century.

Moon after descending node

5 days after its descending node on 25 September 2091 at 00:30 in ♓ Pisces, the Moon is following the southern part of its orbit for the next 9 days, until it will cross the ecliptic from South to North in ascending node on 9 October 2091 at 12:42 in ♍ Virgo.

Draconic month

18 days after beginning of current draconic month in ♍ Virgo, the Moon is moving from the second to the final part of it.

Moon before northern standstill

9 days after previous South standstill on 20 September 2091 at 16:58 in ♑ Capricorn, when Moon has reached southern declination of ∠-18.923°. Next 4 days the lunar orbit moves northward to face North declination of ∠19.007° in the next northern standstill on 5 October 2091 at 08:31 in ♋ Cancer.

Syzygy in 12 days

After 12 days on 12 October 2091 at 18:29 in ♎ Libra, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
