(posting this ahead of time – on the road back to Quito and no Internet for a couple of days)
Sunday January 29th the 2-day old thin waxing crescent 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 2-day old waxing crescent Moon will be over the southwest horizon, below Mars and Venus, at sunset local time. The outer planet Neptune is there but too dim to be seen without some sort of optical assistance.
These two graphics show the sky as viewed from Quito Ecuador at 0o latitude, and my home latitude of approximately 40o North.
