October Moon at Descending Node

   Thursday October 13th the waxing gibbous 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 13-day old waxing gibbous Moon rises around sunset local time and is visible all night, setting at around sunrise. Hidden by the Moon’s reflected light that is brightening the sky is the Andromeda Galaxy, M-31. Once the Moon has moved past this part of the sky M-31 will be visible with binoculars and possibly to the naked eye if your skies are dark enough.
