Moon phase and lunation details

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 27 October 2015 at 12:05.

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 is entering ♋ Cancer

Moon is passing first ∠2° of ♋ Cancer tropical zodiac sector.

Apparent angular diameter ∠1882"

Lunar disc appears visually 2.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1882" and ∠1933".

Hunter Moon before 3 days

Next Full Moon is the Beaver Moon of November 2015 after 25 days on 25 November 2015 at 22:44.

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 195 / 1148

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 195 of Meeus index or 1148 from Brown series.

Synodic month length 29.74 days

Length of current 195 lunation is 29 days, 17 hours and 41 minutes. This is the year's longest synodic month of 2015. It is 59 minutes longer than next lunation 196 length.

Lunation length longer than mean

Length of current synodic month is 4 hours and 57 minutes longer than the mean length of synodic month, but it is still 2 hours and 6 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠192.9°

This lunation true anomaly is ∠192.9°. At the beginning of next synodic month true anomaly will be ∠220.3°. 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 after perigee

4 days after point of perigee on 26 October 2015 at 12:59 in ♈ Aries. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 7 days, until it get to the point of next apogee on 7 November 2015 at 21:48 in ♍ Virgo.

Previous perigeeNext apogee

Distance to Moon 380 962 km

Moon is 380 962 km (236 719 mi) away from Earth on this date. Moon moves farther next 7 days until apogee, when Earth-Moon distance will reach 405 724 km (252 105 mi).

Moon after descending node

6 days after its descending node on 25 October 2015 at 07:37 in ♈ Aries, the Moon is following the southern part of its orbit for the next 7 days, until it will cross the ecliptic from South to North in ascending node on 7 November 2015 at 15:53 in ♍ Virgo.

Draconic month

20 days after beginning of current draconic month in ♎ Libra, the Moon is moving from the second to the final part of it.

Moon in northern standstill

At 09:02 on this date the Moon is meeting its North standstill point, when it will reach northern declination of ∠18.241°. Next 14 days the lunar orbit will move in opposite southward direction to face South declination of ∠-18.331° in its southern standstill point on 15 November 2015 at 00:39 in ♑ Capricorn.

Syzygy in 11 days

After 11 days on 11 November 2015 at 17:47 in ♏ Scorpio, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
