On March 20, 2009, at 1:00 p.m. EDT, join a panel of scientists for a live Sun-Earth Day Webcast on nasa.gov and NASA TV. During the webcast, scientists will share discoveries about the sun, while students monitor the sun and prepare their own space weather forecast. New and exciting images and animations will be shared during the program. 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.
