Moon phase and lunation details

5 days after First Quarter

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.

The Moon is 12 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 231 of Meeus index or 1184 from Brown series.

Synodic month length 29.41 days

Length of current 231 lunation is 29 days, 9 hours and 45 minutes. It is 2 hours and 30 minutes shorter than next lunation 232 length.

Lunation length shorter than mean

Length of current synodic month is 2 hours and 59 minutes shorter than the mean length of synodic month, but it is still 3 hours and 10 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠28°

This New Moon true anomaly is ∠28°. At beginning of next synodic month true anomaly will be ∠49.6°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon after apogee

2 days after point of apogee on 20 September 2018 at 00:54 in ♒ Aquarius. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 13 days, until it get to the point of next perigee on 5 October 2018 at 22:29 in ♌ Leo.

Distance to Moon 403 262 km

Moon is 403 262 km (250 575 mi) away from Earth on this date. Moon moves closer next 13 days until perigee, when Earth-Moon distance will reach 366 396 km (227 668 mi).

Moon after descending node

2 days after its descending node on 20 September 2018 at 09:30 in ♒ Aquarius, the Moon is following the southern part of its orbit for the next 11 days, until it will cross the ecliptic from South to North in ascending node on 4 October 2018 at 03:10 in ♌ Leo.

Moon after southern standstill

4 days after previous South standstill on 18 September 2018 at 09:35 in ♑ Capricorn, when Moon has reached southern declination of ∠-20.909°. Next 10 days the lunar orbit moves northward to face North declination of ∠21.037° in the next northern standstill on 2 October 2018 at 13:03 in ♋ Cancer.

Syzygy in 2 days

After 2 days on 25 September 2018 at 02:53 in ♈ Aries, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
