Observations



SWPC utilizes an array of observed data sets in their Space Weather forecast operations and related research.  Many of these data sets are available in near-real-time, and come from a variety of sources, ranging from solar imaging satellites to ground magnetometer stations.  SWPC also provides these data sources to the external community.
