Seasons without Borders uses the days of the changing of the seasons as a time to explore the motion of the Sun in our sky as we travel around it throughout the year. Groups have special activities for public outreach and education for these interesting days, and some connect with other Affiliates to share observations from different parts of the world. The next Seasons Without Borders event is 21-22 December 2009.
