December Moon at Descending Node

july8-descending-node   Friday December 18th our Moon will be crossing the plane of the ecliptic moving south. This is known as the descending node, one of two intersections the Moon’s orbital path (dark green line) has with the ecliptic.
   
   
   
   

   
   
   On the day of the node crossing the 7.5-day old first quarter Moon rises at about mid-day local time and will be visible over the southern horizon at sunset local time.

   
   
   
   
   
Caution: Objects viewed with an optical aid are further than they appear.
