Waning Gibbous on . The illuminated surface of the moon is 99% and getting smaller. The lunar cycle is 15 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 passing about ∠14° of ♐ Sagittarius tropical zodiac sector.
Previous main lunar phase is the Full Moon before 1 day on 23 May 2100 at 17:25.
Next Full Moon is the Strawberry Moon of June 2100 after 28 days on 22 June 2100 at 01:11.
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 2.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1943" and ∠1894".
The Moon is 15 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1241 of Meeus index or 2194 from Brown series.
The length of this lunation is 29 days, 14 hours and 38 minutes and it is 2 hours and 3 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 54 minutes longer than the mean synodic month length. It is 5 hours and 9 minutes shorter compared to 21st century's longest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠200.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠227.5°.
2 days since point of perigee on 22 May 2100 at 11:04 in ♏ Scorpio the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next apogee on 3 June 2100 at 17:09 in ♈ Aries.
The Moon is 368 989 km (229 279 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 405 537 km (251 989 mi).
6 days after descending node on 18 May 2100 at 10:11 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 6 days until the lunar crosses the ecliptic again from South to North in ascending node on 31 May 2100 at 02:55 in ♓ Pisces.
11 days since the last northern standstill on 12 May 2100 at 13:36 in ♊ Gemini when the Moon has reached North declination of ∠28.277° the lunar orbit is extending southward over the next day to face maximum declination of ∠-28.230° at the point of next southern standstill on 25 May 2100 at 09:50 in ♐ Sagittarius.
20 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the second to the final part of the lunar cycle.
In 14 days on 7 June 2100 at 23:31 in ♊ Gemini 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.
