As told in this month's astronomy podcast, Venus is disappearing in the west after sunset. So September offers you a final chance to see four bright planets at once.
As twilight fades, spot Venus very low in the west-southwest. Upper right of it on September 1st, by just 1.3° is Spica, a 1st-magnitude star but less than 1% as bright as Venus. Can you see Spica naked-eye through the twilight?
