Waxing Gibbous in Aquarius

Waxing Gibbous on . The illuminated surface of the moon is 79% and growing larger. The lunar cycle is 10 days young.

Moonrise and moonset

The 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.

Moon phase and lunation details

Moon in ♒ Aquarius

Moon is passing about ∠8° of ♒ Aquarius tropical zodiac sector.

3 days after First Quarter

Previous main lunar phase is the First Quarter before 3 days on 21 September 2099 at 09:48.

Harvest Moon after 4 days

Next Full Moon is the Harvest Moon of September 2099 after 4 days on 29 September 2099 at 10:45.

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 ∠1808"

Lunar disc appears visually 5.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1808" and ∠1913".

Lunation 1233 / 2186

The Moon is 10 days young and navigating from the first to the middle part of the current synodic month. This is lunation 1233 of Meeus index or 2186 from Brown series.

Synodic month length 29.36 days

The length of this lunation is 29 days, 8 hours and 42 minutes and it is 1 hour and 15 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length shorter than mean

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

Lunar orbit details for

True anomaly ∠355.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠355.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠10.7°.

Moon before apogee

9 days since point of perigee on 14 September 2099 at 23:26 in ♍ Virgo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 4 days until the Moon reaches the point of next apogee on 28 September 2099 at 22:34 in ♓ Pisces.

Distance to Moon 396 452 km

The Moon is 396 452 km (246 344 mi) away from Earth and getting further over the next 4 days until the point apogee when Earth-Moon distance is going to be 406 272 km (252 446 mi).

Moon before ascending node

9 days after descending node on 14 September 2099 at 23:44 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from South to North in ascending node on 28 September 2099 at 14:28 in ♓ Pisces.

Moon after southern standstill

3 days since the last southern standstill on 21 September 2099 at 11:17 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.686° the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠28.657° at the point of next northern standstill on 6 October 2099 at 05:56 in ♊ Gemini.

Draconic month

23 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 4 days

In 4 days on 29 September 2099 at 10:45 in ♈ Aries 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.
