Having three planets align close together is an infrequent event from a human perspective. On Sunday night, Jupiter, Venus and Mercury or all form a tight triangle in the western sky. The best time to look will be between 30 and 60 minutes after sunset. You must have a clear view of the western horizon since the planets will be pretty low at that point.
Let Venus be your guide. It pops out of the fading twilight long before the others. As soon as you locate Venus, look in that direction using binoculars. If your binoculars are typical, all three planets will fit in the eyepiece simultaneously. As the twilight continues to fade, set the optics aside; eventually the triangle will become visible to the naked eye.
