Space Weather Data Documentation

Updated 2023 May 26

CelesTrak has switched to using primary sources, wherever available, for producing the Space Weather Data, to mitigate the introduction of errors and inconsistencies found in some secondary sources. Users should expect to see differences in the data as a result of these improvements.
