96506 Oberösterreich           Discovered 1998 July 26 by E. Meyer at the Davidschlag Observatory, Linz.
Oberösterreich is one of the nine federal states of Austria and one of the most important industrial areas of Austria today. Its capital is Linz, where Johannes Kepler lived from 1612 to 1626 and discovered his third law in 1618. Since 1918 the name Oberösterreich has been official.
