Light Curves
 During
the Spring semester of 2004, Sarah Willis, under the supervision of
Dr. Robert Mutel, observed 5 asteroids using the Rigel
telescope at multiple epochs to determine their rotation periods. The
results were submitted to the CALL
website and a research paper will be submitted to the Minor
Planet Bulletin by the end of the semester. Click on the plot at
