Paper Plate Education
Activity: Tracking Sunspots
Important: Do not look directly at the sun. Either use only proper filters on telescopes or project the image.
Project, trace, and track sunspots directly on a plate which defines the
outline of the sun.
View sunspots through a properly filtered telescope (see http://www.transitofvenus.org/safety.htm) and transfer what you see onto a paper plate that represents the solar disk. Compare a series of plates from successive days to track sunspots and to predict the rotational period of the sun.
