Solar Data Analysis Center (SDAC)

NASA's Solar Data Analysis Center provides a variety of routes to current and past solar images and digital data. Links on the home page (http://umbra.nascom.nasa.gov) will bring you quickly up-to-date on the current state of the sun and its surrounding atmosphere (the corona).

Try the SDAC DataFinder for quick access to space solar physics data. This service provides quick links to finding data from most NASA missions. The list includes:

VSO
RHESSI
SOHO
SOHO EIT
STEREO
Solar-B
TRACE
Yohkoh
CGRO solar flares
SMM
OSO-7
and Special Atlases

Of particular interest is the Virtual Solar Observatory (VSO), which provides a route to data files from the above missions and many ground-based observatories.

You can also explore links to other sources of solar data such as the National Solar Observatory.
