SKETCHING SUNSPOTS

Sketching sunspots is easiest using the projection method. Decide on a standard size of sketch—6 inches (150 mm) is common—and prepare blank forms ahead of time with a circle for the Sun's diameter and places to note date and time, weather, seeing conditions, and the equipment you used.

Tape the blank onto the projection screen, adjust it so the Sun just fills the circle, and with an HB or softer pencil, lightly trace the locations of the sunspots.

By making regular sketches, you can produce a record of the changing face of the Sun.
