If it's clear this Sunday night, Sept. 8, go out shortly after sunset and look for the moon and brilliant Venus low in the west-southwest. They will be only 1.5 degrees apart: a little over the width of a finger at arm's length. If you miss out on Sunday night, try again Monday. The moon will still be in that part of the sky, but a little fatter and farther to the left. Image made with Stellarium.
