Sun-Earth Day is comprised of a series of programs and events that occur throughout the year culminating with a celebration on or near the Spring Equinox. For Sun-Earth Day 2009, NASA will engage a worldwide audience in the celebration of the International Year of Astronomy, with an emphasis on daytime astronomy. Tremendous strides have been made as satellites and ground-based observatories attentively monitor the sun to understand the processes that govern the sun's influence on the solar system. NASA will offer a series of coordinated events to promote and highlight the sun and its connection to Earth and other planets. The events will support the spirit of international collaboration.

Over the past eight years, the NASA Sun-Earth Connection Education Forum has sponsored and coordinated education and public outreach events to highlight NASA Sun-Earth Connection research and discoveries. The Forum's strategy involves using celestial events, such as total solar eclipses and the Transit of Venus, as well as Sun-Earth Day during the March equinox, to engage K-12 schools and the public in space science activities, demonstrations, and interactions with space scientists.

On March 20, 2009, at 1:00 p.m. EST, join a panel of scientists for a live Sun-Earth Day Webcast. During the webcast, scientists Eric Christian, Nicky Fox, Terry Kucera and Sten Odenwald will share discoveries about the sun, while students monitor the sun and prepare their own space weather forecast. New and exciting images and visualizations will be shared during the program.
