Sperry Observatory will be open on October 15 &16 from 12-5 pm, for the “Four Centuries in a Weekend” history event!

Come spend the weekend at Sperry during this annual Union County celebration of historic houses and sites.

Sperry will be open for tours, and Amateur Astronomers Inc. members will be available to answer your astronomy questions.

We will also be distributing gently-used astronomy and science-related books, magazines, and posters that were donated for this purpose.
