Sun Day (May 3, 1978) was designated by Jimmy Carter President of United States of America specifically devoted to advocacy for solar power,following a joint resolution by Congress. It was modelled on the highly successful Earth Day of April 22, 1970.
International Sun day has been celebrated over the past seven years on May 3, 2008. The day is sponsored and celebrated by NASA. Its Sun-Earth connection education forum organizes and coordinates events to highlight NASA Sun-Earth Connection research and discoveries. Sun-Earth Day is during the March equinox.
The celebration on the day is marked by the celestial events, such as total solar eclipses and the Transit of Venus, and Sun-Earth Day during the March Equinox. They participate in space science activities, demonstrations, and various interactive sessions and quiz with space scientists.
One of main goals of the day is to help scientists understand the interactions between the Sun and the Earth's environment, which will definitely facilitate them to predict the Sun's activity and motion, and thus, space weather conditions.
