Equinoxes, Solstices and Seasonal Changes Workshop

Ever wonder why we have seasons?  What's the meaning of equinoxes and solstices?  Come join Dr. Allen Franz for a discussion of the celestial mechanics that shape these phenomena--and get a better sense of Earth's place in the Solar System and how it helps explain our climate here in Southern California. 1600 W. Paseo del Mar, San Pedro. RSVP at www.pvplc.org, Events & Activities.
