NASA’s Solar Dynamics Observatory provides solar imagery and data from instruments studying the Sun’s atmosphere.
NASA’s Solar Data Analysis Center serves solar images, data, news, and research resources from missions including SOHO and PUNCH.
About SDAC
The Solar Data Analysis Center (SDAC) is a NASA website run from the Solar Physics Laboratory at NASA Goddard Space Flight Center in Greenbelt, Maryland. It serves solar images, solar data, news, and research resources, and it develops and maintains scientific research infrastructure that supports NASA's Heliophysics Science Division.
The site provides access to data from missions including SOHO and PUNCH. PUNCH data is available through the Virtual Solar Observatory or by direct download from SDAC. The Solar Monitor, formerly the Active Region Monitor, presents solar activity information, including images, solar flare locations, and flare predictions. The homepage also links to an external LMSAL events page showing soft X-ray, energetic proton, and solar wind data. Pricing is unknown, and the source does not state any geographic or usage limits.
