C.6 Solar System Observations Changes to text and point of contact.

C.6 Solar System Observations (SSO) supports primarily ground-based and limited airborne- and space-based astronomical observations of bodies in our Solar System. Proposals are solicited for observations over the entire range of wavelengths, from the ultraviolet to radio, that contribute to the understanding of the nature and evolution of the Solar System and its individual constituents.

The following changes will be made to C.6 Solar System Observations on or about March 12, 2020: 1) What was formerly Section 2.2 "Proposals Utilizing Goldstone Planetary Radar" has been removed. 2) A new Section 2.2, entitled Exclusions, has been added and 3) The point of contact for this program element (see Section 5) has changed. The due dates remain unchanged: Step-1 proposals are due April 8, 2020 and Step-2 proposals are due June 10, 2020. New text is in bold and deleted text is struck through.
