= Virtual Solar Observatory = == Welcome to the Virtual Solar Observatory! For the latest VSO updates, check out our [[https://docs.virtualsolar.org/wiki/News|News]] page. == The VSO is a tool for investigating the physics of the Sun. Users may search existing databases for terrestrial and space-based observations, hiding the details of where the data is and what’s needed to get it. A researcher can use the VSO to search across multiple instruments and events, to find datasets of interest, and having done that, transparently download them to their workstation. There are many ways to use the VSO to search and download data. The main two ways are: 1. Via our [http://virtualsolar.org web interface] and 2. Via [http://www.lmsal.com/solarsoft/ssw_whatitis.html SolarSoft] in IDL Because we publish our API, users can use their favorite programming language to access the VSO including [http://sunpy.org/ SunPy] and [https://docs.virtualsolar.org/WSDL WSDL]. The VSO web and data interfaces are a singular model mirrored across multiple sites such as the NASA Solar Data Archive Center, the National Solar Observatory and the Smithsonian Astrophysical Observatory. The data archives themselves are distributed, residing with the groups that designed, built and used the instruments to collect the data; they possess the expertise required to fully exploit the data. {{{ #!html

}}} == Data Products == We have observations available from sources as diverse as NASA’s space-bourne Solar Dynamics Observatory and the ground-based GONG instrument. Observations go back nearly 100 years, such as from the Mt Wilson 60ft spectro-heliograph. We are proud of our international partnerships and we are always looking to serve more data whenever possible. A current list of our data providers can be found here: [http://vso.nascom.nasa.gov/cgi-bin/show_details.pl?keyword=PROVIDER] Our data is generally provided as FITS files but may also be in other standards, such as XML or HDF. * Check out our [[https://docs.virtualsolar.org/wiki/News|News]] page for new and updated datasets == Contact Us == If you have problems with this site, please [wiki:ContactUs contact the site admin], with the nature of the problem.
