Altitude, next 24 hours WHEN EACH SOURCE IS UP
Each line is a source's height above your horizon. Above the dashed line it clears your dish horizon; the peak of each curve is when it crosses your meridian.
Milky Way overhead
Galactic latitude of your beam over the next 24 hours. Hydrogen is strongest inside the shaded band, when the Milky Way's disk drifts through.

Flux is at 1.4 GHz in janskys, a guide to what's loud. "Point dish to" is the elevation to set, due north or south, so the source drifts through your beam. "Drifts through your beam" means your current pointing already catches it when it crosses the meridian.
