On September 18, 1997, many stargazers in the U. S.

Using a 1.2 meter reflector [ http://cfa-www.harv ], astronomer Kris Stanek had an excellent view of this [ http://cfa-www.harv ] dream-like event from the Whipple Observatory [ http://linmax.sao.a ] atop Arizona's Mount Hopkins [ http://cfa-www.harv ]. This animated gif image was constructed by Wes Colley from 4 frames taken by Stanek at 35 second intervals as the ringed planet emerged from behind the Moon's [ http://antwrp.gsfc. ] dark limb.
