Notice: The use of SOHO images or data for public education efforts and non-commercial purposes is strongly encouraged and requires no expressed authorization. It is requested, however, that any such use properly attributes the source of the images or data as:

"Courtesy of SOHO/[ instrument ] consortium. SOHO is a project of international cooperation between ESA and NASA."

where [ instrument ] stands for the name of the instrument that acquired the data (i.e. SOHO/EIT, SOHO/LASCO, etc).

Another, shorter, version of the notice: "SOHO (ESA & NASA)" is also acceptable.
