Waning Gibbous on . The illuminated surface of the moon is 90% and getting smaller. The lunar cycle is 17 days old.
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.

Main moon phases of the following lunar cycle.
Moon is leaving the last ∠1° of ♑ Capricorn tropical zodiac sector and will enter ♒ Aquarius later.
Previous main lunar phase is the Full Moon before 3 days on 9 June 2055 at 11:36.
Next Full Moon is the Buck Moon of July 2055 after 26 days on 8 July 2055 at 22:11.
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.
Lunar disc appears visually 3.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1821" and ∠1889".
The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 685 of Meeus index or 1638 from Brown series.
The length of this lunation is 29 days, 11 hours and 18 minutes and it is 1 hour and 46 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°).
The length of the current synodic month is 1 hour and 26 minutes shorter than the mean synodic month length. It is 4 hours and 43 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠254.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠288.5°.
7 days since point of perigee on 5 June 2055 at 06:32 in ♎ Libra the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next apogee on 17 June 2055 at 13:16 in ♓ Pisces.
The Moon is 393 630 km (244 590 mi) away from Earth and getting further over the next 5 days until the point apogee when Earth-Moon distance is going to be 404 162 km (251 135 mi).
11 days after ascending node on 31 May 2055 at 13:01 in ♌ Leo the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 13 June 2055 at 11:33 in ♒ Aquarius.
1 day since the last southern standstill on 11 June 2055 at 02:05 in ♑ Capricorn when the Moon has reached South declination of ∠-20.408° the lunar orbit is extending northward over the next 13 days to face maximum declination of ∠20.427° at the point of next northern standstill on 25 June 2055 at 12:46 in ♋ Cancer.
11 days since the beginning of this draconic month in ♌ Leo the Moon is navigating from the beginning to the first part of the lunar cycle.
In 12 days on 25 June 2055 at 00:15 in ♋ Cancer 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.
