Waning Gibbous in Virgo

Waning Gibbous on . Illuminated surface of the Moon is 98% and getting smaller. Lunar cycle is 16 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 ♍ Virgo

Moon is passing first ∠3° of ♍ Virgo tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 3 February 2015 at 23:09.

Snow Moon before 1 day

Next Full Moon is the Worm Moon of March 2015 after 28 days on 5 March 2015 at 18:06.

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Apparent angular diameter ∠1768"

Lunar disc appears visually 9.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1946".

Lunation 186 / 1139

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 186 of Meeus index or 1139 from Brown series.

Synodic month length 29.44 days

The length of this lunation is 29 days, 10 hours and 34 minutes and it is 45 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 2 hours and 10 minutes shorter than the mean synodic month length. It is 3 hours and 59 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠338.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠338.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠354.5°.

Moon before apogee

14 days since point of perigee on 21 January 2015 at 20:06 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 day until the Moon reaches the point of next apogee on 6 February 2015 at 06:25 in ♍ Virgo.

Distance to Moon 405 411 km

The Moon is 405 411 km (251 911 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 406 155 km (252 373 mi).

Moon before ascending node

11 days after descending node on 25 January 2015 at 10:23 in ♈ Aries the Moon is positioned south of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from South to North in ascending node on 8 February 2015 at 17:10 in ♎ Libra.

Moon after northern standstill

5 days since the last northern standstill on 31 January 2015 at 00:59 in ♋ Cancer when the Moon has reached North declination of ∠18.513° the lunar orbit is extending southward over the next 9 days to face maximum declination of ∠-18.402° at the point of next southern standstill on 14 February 2015 at 17:17 in ♐ Sagittarius.

Draconic month

23 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 18 February 2015 at 23:47 in ♒ Aquarius 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.
