"The third asteroid discovered, by Karl L. Harding on 1804-09-01,
reached opposition last Saturday night Arizona time. Here's a link to a
14-frame animation showing the retrograde motion of the asteroid at 15
minute intervals as seen from Sonoran Desert National Monument that
night. Each exposure was five minutes taken with a Canon 400D at ISO 800
through a Synta 80 mm f/7.5 ED refractor. The faintest stars visible are
about magnitude 16.5. The asteroid itself was about magnitude 10.2
according to XEphem."

  The link, of course, was in the first message. Sheesh!
