Waning Gibbous in Cancer

Waning Gibbous on . Illuminated surface of the Moon is 79% and getting smaller. Lunar cycle is 19 days old.

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.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon is entering ♋ Cancer

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

3 days after Full Moon

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

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.

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.

Apparent angular diameter ∠1882"

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

Lunation 195 / 1148

The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 195 of Meeus index or 1148 from Brown series.

Synodic month length 29.74 days

The length of this lunation is 29 days, 17 hours and 41 minutes and it is 59 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2015. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length longer than mean

The length of the current synodic month is 4 hours and 57 minutes longer than the mean synodic month length. It is 2 hours and 6 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠192.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠192.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠220.3°.

Moon after perigee

4 days since point of perigee on 26 October 2015 at 12:59 in ♈ Aries the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next apogee on 7 November 2015 at 21:48 in ♍ Virgo.

Distance to Moon 380 962 km

The Moon is 380 962 km (236 719 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 405 724 km (252 105 mi).

Moon after descending node

6 days after descending node on 25 October 2015 at 07:37 in ♈ Aries the Moon is positioned south of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from South to North in ascending node on 7 November 2015 at 15:53 in ♍ Virgo.

Moon at northern standstill

At 09:02 the Moon is meeting its standstill point to reach North declination of ∠18.241°. Over the upcoming 14 days the lunar orbit is going to tilt southward to face maximum declination of ∠-18.331° at the point of next southern standstill in ♑ Capricorn on 15 November 2015 at 00:39.

Draconic month

20 days since the beginning of this draconic month in ♎ Libra the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 11 days

In 11 days on 11 November 2015 at 17:47 in ♏ Scorpio the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
