This geocache is named for the brightest star in our sky – Sirius, which resides in the constellation Canis Major. Sirius is, in fact, a binary star. It takes good binoculars to see the two as separate objects. But this is not a two-part cache, just a quick cache and dash.
Bring your own pen or pencil, and be sure that the plastic bag is entirely inside the container when closing and replacing it.
