Description
Summary:The method developed by Richard Carrington nearly 150 years ago is still very useful in order to determine the sunspot heliographic coordinates, owing to its simplicity and low cost equipment required. In this paper, we present a very detailed explanation of the procedure, along with an example of an application. With regard to this, the method can be employed successfully for educational purposes, due to the noticeable accuracy that it provides using a simple instrumental setup.
