Waning Crescent in Virgo

Waning Crescent on . Illuminated surface of the Moon is 1% and getting smaller. Lunar cycle is 28 days old.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

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 ∠1° of ♍ Virgo tropical zodiac sector.

5 days after Last Quarter

Previous main lunar phase is the Last Quarter before 5 days on 1 September 2010 at 17:22.

Harvest Moon after 15 days

Next Full Moon is the Harvest Moon of September 2010 after 15 days on 23 September 2010 at 09:17.

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 ∠1972"

Lunar disc appears visually 3.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1904".

Lunation 131 / 1084

The Moon is 28 days old and navigating from the second to the final part of the current synodic month. This is lunation 131 of Meeus index or 1084 from Brown series.

Synodic month length 29.31 days

The length of this lunation is 29 days, 7 hours and 22 minutes and it is 53 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2010. 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 5 hours and 22 minutes shorter than the mean synodic month length. It is 47 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠349.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠349.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠4.6°.

Moon before perigee

13 days since point of apogee on 25 August 2010 at 05:51 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next day until the Moon reaches the point of next perigee on 8 September 2010 at 04:00 in ♍ Virgo.

Distance to Moon 363 399 km

The Moon is 363 399 km (225 806 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 357 193 km (221 949 mi).

Moon after descending node

3 days after descending node on 4 September 2010 at 00:16 in ♋ Cancer the Moon is positioned south of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from South to North in ascending node on 16 September 2010 at 13:56 in ♑ Capricorn.

Moon after northern standstill

5 days since the last northern standstill on 2 September 2010 at 11:20 in ♊ Gemini when the Moon has reached North declination of ∠24.807° the lunar orbit is extending southward over the next 7 days to face maximum declination of ∠-24.710° at the point of next southern standstill on 14 September 2010 at 23:47 in ♐ Sagittarius.

Draconic month

17 days since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 1 day

In 1 day on 8 September 2010 at 10:30 in ♍ Virgo 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.
