Waning Gibbous on . The illuminated surface of the moon is 98% and getting smaller. The lunar cycle is 16 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 ∠17° of ♍ Virgo tropical zodiac sector.
Previous main lunar phase is the Full Moon before 1 day on 18 February 2011 at 08:36.
Next Full Moon is the Worm Moon of March 2011 after 28 days on 19 March 2011 at 18:10.
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 1.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1971" and ∠1941".
The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 137 of Meeus index or 1090 from Brown series.
The length of this lunation is 29 days, 18 hours and 15 minutes and it is 29 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2011. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
The length of the current synodic month is 5 hours and 31 minutes longer than the mean synodic month length. It is 1 hour and 32 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 ∠139.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠167°.
Moon is at perigee at 07:27 about 12 days since last apogee on 6 February 2011 at 23:13 in ♓ Pisces the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 14 days until point of next apogee on 6 March 2011 at 07:50 in ♈ Aries.
This perigee Moon is 358 247 km (222 604 mi) away from Earth. It is 4 261 km closer than the mean perigee distance, but it is still 12 109 km further than the closest perigee of 21st century.
5 days after descending node on 14 February 2011 at 08:14 in ♋ Cancer the Moon is positioned south of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from South to North in ascending node on 26 February 2011 at 20:19 in ♐ Sagittarius.
6 days since the last northern standstill on 13 February 2011 at 09:00 in ♊ Gemini when the Moon has reached North declination of ∠24.080° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-23.985° at the point of next southern standstill on 25 February 2011 at 22:13 in ♐ Sagittarius.
19 days since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the second to the final part of the lunar cycle.
In 13 days on 4 March 2011 at 20:46 in ♓ Pisces 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.
