Tuesday evening September 15th the thin 2.5-day young waxing crescent Moon will be near the bluish-white star Spica in the constellation Virgo the Harvest Maiden. Both of which, the Moon and Spica, are low over the western horizon at sunset local time. This graphic is set for just after sunset local time and shows the location of a couple of the Dwarf Planets and the innermost planet (the ‘Innie’), Mercury. What Luna passed was that on Monday evening the even thinner waxing crescent Moon was near Mercury, however from a mid-northern latitude perspective the two were low above the horizon and relatively close to the Sun making them a challenge to see.
Mercury is actually best viewed from the southern hemisphere this month. Here is a graphic showing the same view at the same date and time however from 90o south of my location at the southern latitude of 40oS.
