Waxing Gibbous in Leo

Waxing Gibbous on . Illuminated surface of the Moon is 97% and growing larger. Lunar cycle is 13 days young.

Moonrise and moonset

Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon is entering ♌ Leo

Moon is passing first ∠1° of ♌ Leo tropical zodiac sector.

5 days after First Quarter

Previous main lunar phase is the First Quarter before 5 days on 4 February 2017 at 04:19.

Snow Moon after 1 day

Next Full Moon is the Snow Moon of February 2017 after 1 day on 11 February 2017 at 00:33.

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 ∠1919"

Lunar disc appears visually 1.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1919" and ∠1944".

Lunation 211 / 1164

The Moon is 13 days young and navigating from the first to the middle part of the current synodic month. This is lunation 211 of Meeus index or 1164 from Brown series.

Synodic month length 29.62 days

The length of this lunation is 29 days, 14 hours and 51 minutes and it is 2 hours and 52 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 longer than mean

The length of the current synodic month is 2 hours and 7 minutes longer than the mean synodic month length. It is 4 hours and 56 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠259.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠259.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠295°.

Moon after perigee

2 days since point of perigee on 6 February 2017 at 13:59 in ♊ Gemini the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next apogee on 18 February 2017 at 21:14 in ♏ Scorpio.

Distance to Moon 373 544 km

The Moon is 373 544 km (232 109 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 404 376 km (251 268 mi).

Moon before ascending node

10 days after descending node on 29 January 2017 at 22:21 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from South to North in ascending node on 11 February 2017 at 19:49 in ♌ Leo.

Moon after northern standstill

1 day since the last northern standstill on 7 February 2017 at 18:34 in ♊ Gemini when the Moon has reached North declination of ∠18.865° the lunar orbit is extending southward over the next 12 days to face maximum declination of ∠-18.848° at the point of next southern standstill on 21 February 2017 at 20:50 in ♑ Capricorn.

Draconic month

25 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 1 day

In 1 day on 11 February 2017 at 00:33 in ♌ Leo the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
