LASCO images have been used by the SWPC forecast office to characterize the solar corona heating and transient events, including CME’s, and to see the effects of the corona on the solar wind. More recently, the LASCO images are vital to the WSA-Enlil model that became operational in October of 2011. WSA-Enlil has become an important tool for forecasting the impact of Coronal Mass Ejections and the effects of the Solar Wind on the Earth.
