Waxing Gibbous in Aries

Waxing Gibbous on . Illuminated surface of the Moon is 94% and growing larger. Lunar cycle is 12 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 ♈ Aries

Moon is passing first ∠4° of ♈ Aries tropical zodiac sector.

4 days after First Quarter

Previous main lunar phase is the First Quarter before 4 days on 20 October 2015 at 20:31.

Hunter Moon after 2 days

Next Full Moon is the Hunter Moon of October 2015 after 2 days on 27 October 2015 at 12:05.

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 ∠1973"

Lunar disc appears visually 2.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1930".

Lunation 195 / 1148

The Moon is 12 days young and navigating from the first to the middle part of the current synodic month. This is lunation 195 of Meeus index or 1148 from Brown series.

Synodic month length 29.74 days

The length of this lunation is 29 days, 17 hours and 41 minutes and it is 59 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2015. 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 4 hours and 57 minutes longer than the mean synodic month length. It is 2 hours and 6 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠192.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠192.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠220.3°.

Moon before perigee

13 days since point of apogee on 11 October 2015 at 13:17 in ♍ Virgo 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 26 October 2015 at 12:59 in ♈ Aries.

Distance to Moon 363 313 km

The Moon is 363 313 km (225 752 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 358 464 km (222 739 mi).

Moon in descending node

Moon is in descending node in ♈ Aries at 07:37 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 13 days until Moon's next ascending node later on 7 November 2015 at 15:53 in ♍ Virgo.

Moon before northern standstill

6 days since the last southern standstill on 18 October 2015 at 18:31 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.190° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠18.241° at the point of next northern standstill on 31 October 2015 at 09:02 in ♊ Gemini.

Draconic month

14 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 2 days

In 2 days on 27 October 2015 at 12:05 in ♉ Taurus 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.
