Signs and Seasons by Jay Ryan

Signs & Seasons: Understanding the Elements of Classical Astronomy


by Jay Ryan

The goal of Signs & Seasons is to help the reader become an outdoor observer of the sky, and to understand how the sky is the foundation for timekeeping and navigation—according to the cycles of the sun, moon, and stars.

Signs & Seasons is the recommended textbook for the Experience Astronomy Basic course, and it is required for the Advanced course.
