Join us on Astronomy Day with renowned astronomer, Randy Rhea for a fascinating program on our sun--how it works, how it changes, and how it affects life on Earth. Now is a period of high solar activity. It is the cause of the recent outburst of the Northern Lights, and it could happen again soon. In 1989, a solar flare knocked out the power grid in Quebec for nine hours. In this high-tech age, solar flares have the potential for much greater damage.This program will be held in the Learning Center at Pebble Hill Plantation and will include a lecture and outdoor segment with Rhea's high-powered telescope.
