Waning Gibbous in Leo

Waning Gibbous on . Illuminated surface of the Moon is 95% and getting smaller. Lunar cycle is 17 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 in ♌ Leo

Moon is passing about ∠13° of ♌ Leo tropical zodiac sector.

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 5 January 2015 at 04:53.

Wolf Moon before 2 days

Next Full Moon is the Snow Moon of February 2015 after 27 days on 3 February 2015 at 23:09.

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 ∠1775"

Lunar disc appears visually 9.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1775" and ∠1951".

Lunation 185 / 1138

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 185 of Meeus index or 1138 from Brown series.

Synodic month length 29.48 days

The length of this lunation is 29 days, 11 hours and 38 minutes and it is 1 hour and 4 minutes longer than the upcoming lunation's length. 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 shorter than mean

The length of the current synodic month is 1 hour and 6 minutes shorter than the mean synodic month length. It is 5 hours and 3 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠318°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠318° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠338.3°.

Moon before apogee

13 days since point of perigee on 24 December 2014 at 16:43 in ♒ Aquarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next apogee on 9 January 2015 at 18:17 in ♍ Virgo.

Distance to Moon 403 771 km

The Moon is 403 771 km (250 892 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 405 411 km (251 911 mi).

Moon before ascending node

9 days after descending node on 29 December 2014 at 09:27 in ♈ Aries the Moon is positioned south of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from South to North in ascending node on 12 January 2015 at 15:33 in ♎ Libra.

Moon after northern standstill

3 days since the last northern standstill on 3 January 2015 at 17:53 in ♊ Gemini when the Moon has reached North declination of ∠18.650° the lunar orbit is extending southward over the next 10 days to face maximum declination of ∠-18.577° at the point of next southern standstill on 18 January 2015 at 06:17 in ♐ Sagittarius.

Draconic month

21 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 13 days

In 13 days on 20 January 2015 at 13:14 in ♑ Capricorn 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.
