摘要：The National Weather Service Space Weather Predic- tion Center (SWPC) recently released two new forecast products, a 3-Day Forecast and a corresponding Forecast Discussion. Both are produced at 0030 and 1230 UTC with an option for out-of-cycle updates during significant space weather events. With the increasing dependence on and prevalence of technologies affected by space weather, the space weather customer base continues to expand. The goal of these new products is to communicate forecast information in more frequent and more easily understood manner to this broadening customer base. These new products evolved from the traditional daily Report of Solar and Geophysical Activity (RSGA).
