Waning Gibbous in Pisces

Waning Gibbous on . The illuminated surface of the moon is 99% and getting smaller. The lunar cycle is 16 days old.

Moonrise and moonset

The moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon phase and lunation details

Moon in ♓ Pisces

Moon is passing about ∠5° of ♓ Pisces tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 13 August 2030 at 10:44.

Sturgeon Moon before 1 day

Next Full Moon is the Harvest Moon of September 2030 after 28 days on 11 September 2030 at 21:18.

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 ∠1877"

Lunar disc appears visually 0.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1877" and ∠1894".

Lunation 378 / 1331

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 378 of Meeus index or 1331 from Brown series.

Synodic month length 29.5 days

The length of this lunation is 29 days, 11 hours and 56 minutes and it is 1 hour and 9 minutes longer than the upcoming lunation's length. 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 shorter than mean

The length of the current synodic month is 48 minutes shorter than the mean synodic month length. It is 5 hours and 21 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠244.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠244.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠279.9°.

Moon after perigee

4 days since point of perigee on 9 August 2030 at 22:50 in ♐ Sagittarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next apogee on 21 August 2030 at 22:49 in ♊ Gemini.

Distance to Moon 381 844 km

The Moon is 381 844 km (237 267 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 404 174 km (251 142 mi).

Moon after ascending node

5 days after ascending node on 8 August 2030 at 19:44 in ♐ Sagittarius the Moon is positioned north of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from North to South in descending node on 22 August 2030 at 08:09 in ♊ Gemini.

Moon after southern standstill

5 days since the last southern standstill on 9 August 2030 at 01:58 in ♐ Sagittarius when the Moon has reached South declination of ∠-22.572° the lunar orbit is extending northward over the next 8 days to face maximum declination of ∠22.465° at the point of next northern standstill on 22 August 2030 at 18:22 in ♊ Gemini.

Draconic month

5 days since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 14 days

In 14 days on 28 August 2030 at 23:07 in ♌ Leo 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.
