Moon phase and lunation details

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 21 August 2011 at 21:55.

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.

Moon in ♊ Gemini

Moon is passing about ∠18° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1821"

Lunar disc appears visually 4.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1821" and ∠1898".

Harvest Moon after 19 days

Next Full Moon is the Harvest Moon of September 2011 after 19 days on 12 September 2011 at 09:27.

Upcoming main Moon phases

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.

Lunation 143 / 1096

The Moon is 23 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 143 of Meeus index or 1096 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.35 days

The length of the lunation is 29 days, 8 hours and 24 minutes. It is 19 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the 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 4 hours and 20 minutes shorter than the mean synodic month length. It is 1 hour and 49 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠312.1°

At the beginning of the lunation cycle the true anomaly is ∠312.1°. At the beginning of next synodic month the true anomaly is going to be ∠333.4°.

Moon after apogee

4 days after point of apogee on 18 August 2011 at 16:23 in ♈ Aries. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 7 days, until the Moon reaches the point of next perigee on 30 August 2011 at 17:35 in ♍ Virgo.

Previous apogeeNext perigee

Distance to Moon 393 546 km

The Moon is 393 546 km (244 538 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 360 858 km (224 227 mi).

Moon in descending node

Moon is in descending node in ♊ Gemini at 17:23 crossing the ecliptic from North to South to meet ascending node 12 days later on 5 September 2011 at 07:36 in ♐ Sagittarius.

Previous nodeNext node

Draconic month

14 days since the beginning of current draconic month in ♐ Sagittarius, the Moon is navigating from the second to the final part of the cycle.

Moon at northern standstill

At 12:17 the Moon is meeting its standstill point to reach North declination of ∠23.149°. Over the next 12 days the lunar orbit is going to extend southward to face maximum declination of ∠-23.047° at the point of next standstill in ♐ Sagittarius on 5 September 2011 at 05:01.

Previous standstillNext standstill

Syzygy in 5 days

In 5 days on 29 August 2011 at 03:04 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.
