The
SAS Citizen Scientist Observatory Registry
A White Paper by Sheldon Greaves, Ph.D.

This project has two purposes. First,
to create a community where science enthusiasts
can enter their area of interest by observing—
something that most people would not consider
beyond their capabilities. Second, it
would build a collection of useful data
to be consulted by both amateur and professional
scientists on a range of subjects.
