- Solar noon & winter solstice, with sunshine, at the UO's temporary obelisk
-
Three minutes past solar noon on Friday, Dec. 21, the shadow of the temporary obelisk on Memorial Quad reaches toward 13th Avenue (click on the photo to view a short movie of the shadow!). History professor John Nicols and physics professor Gregory Bothun were on the site to measure the shadow in conjunction with winter solstice and to talk to the media about potential plans for a permanent structure on campus that marks time with an ancient science and pays tribute to campus scholarship. See the live obelisk Webcam. (The temporary wooden obelisk will removed soon; it was constructed in June 2007 in time for summer solstice.)
