The project observing time is planned to be distributed as:

• Core Program (CP)

• National Programs (NP)

• Open Time for the International Community (OT)

The Core Programme will be designed by a Core Programme Team and should be carried out during the first 2 years of the project. The time for Funding Bodies Programs is allocated by a national panel for each of the countries involved in the implementation process of WSO-UV. The observing time granted for each country will be proportional to its contribution to the project. There will be a large fraction (up to 40 percent) of Open Time for the International Community. First call for proposals for national and open times will be one year before launch.
