The presentation focused on two major questions: (1) How do anthropologists reconstruct the health of prehistoric people?  (2) What have we learned from the reconstruction of prehistoric health?

John Deere Lecture Hall, Augustana College
 
The perihelion date for Comet Hale-Bopp was April 1, 1997. On March 26 we shared information about the comet's characteristics and viewed some images of the comet.

From 7:30 to 8:30 pm about 60 people looked at Comet Hale-Bopp in the on-campus observatory. The sky was perfectly clear! The sun set at 6:21 pm and the comet's altitude at 7:30 was about 22 degrees. We also looked at it with 7 x 50 binoculars. The tail was magnificent! Later, about 9:00 pm, Mike Shaw (an Augustana student) and David Renneke took some pictures of the comet using an ST-6 CCD camera and an 85 mm lens mounted piggyback on a telescope. The comet was still visible at 10:00 pm when the Augustana observatory was closed. It set at 11:16 pm.
