The First Quarter Moon is Thursday January 21, this is an apogee First Quarter Moon. The bright planet Venus is low in the twilight morning skies. Jupiter Mercury and Saturn are very low in the twilight skies. The Moon is close to the trio on the 14th but this conjunction will be difficult to see. Dimming but still bright Mars now dominates the evening skies. On the 21st Mars is near the First Quarter moon, with Uranus in between.

The First Quarter Moon is Thursday January 21, this is an apogee First Quarter Moon, where the moon is furthest from the Earth.It will be interesting to compare this last quarter Moon with the Perigee First quarter Moon of November 19 and December 19.
