15497 Lucca           Discovered 1999 Feb. 23 by S. Donati at Agliale Mount Observatory.
The ancient city of Lucca, on the banks of the river Serchio, is the capital of Tuscany. It is in the center of a very fertile valley and is surrounded by hills. On one of these hills there can be found the Agliale Mount Observatory, from which this minor planet was discovered.
