Solar Joint Observing Programs (JOPs)

Please send updates to soc (at) esa.nascom.nasa.gov

What are JOPs?

JOPs are an effort by the SOHO Science Planning Working Group to produce coherent plans whereby various SOHO instruments can maximize their scientific return by coordinating their individual observing plans for the study of specific solar phenomena. Many JOPs involve collaborations with other ground-based or space-based observatories.

If you would like to write and run a JOP, please follow the JOP Guidelines.

If you have any questions about a specific JOP or its objectives, please feel free to contact the JOP organizer listed under the specific JOP.

If no format is specified, the JOP document is in HTML, plain text or Adobe Portable Document format.
