Tonight, a clear western horizon shows Venus.
I imagine a line to the sunset
which intersects Mercury below it but ascending
each night while Venus descends, their conjunction
next week even if we don’t notice.

From mid-May through the end of the month, Mercury is visible after sunset below Venus above where the Sun set. Past mid-month, Mercury ascends while Venus descends toward its June 3 passage between the Earth and the Sun and their conjunction will come May 20/21.
